IPM NEWS --- international IPM news and programs

I. IPM NEWS / APPLICATIONS international IPM news and programs U.S. 1997 IPM Budget Survives The United States' budget for federally-supported IPM programs in fiscal 1997 will total US million, the same level as 1996with no cuts, according to a late September report from the Integrated Pest Management Program centered in the U.S. Department of Agriculture's (USDA) Cooperative State Research, Education, and Extension Service. A requested increase of US million, half for research and half for extension, was not approved, however. The funding increase would have supported large-scale competitive grants. Nonetheless, IPM remains a strongly emphasized program in the USDA budget for 1998, with ardent continuing support from top level USDA personnel.

In a related activity, federal officials and others are investigating the possibilities of making crop insurance coverage available to growers who participate in large-scale IPM demonstration projects; officials are also gathering data to give to the Federal Crop Insurance entity showing that growers who use defined IPM practices have lower risks and therefore should be entitled to lower insurance rates.

Victoria Parliament Investigates Weeds' Impacts The impact of pest plants (weeds) the damage they can cause, and the costs to control them has triggered a full-scale government inquiry by The Parliament of Victoria (Australia). A Parliamentary committee is investigating not only impacts and costs, but the adequacy of current research and information dissemination concerning pest plant control and management strategies, as well as the appropriate roles of State and local governments, industry, and growers.

The investigation divides pest plants into two broad groups: environmental weeds, and agricultural weeds, though the categories are not mutually exclusive. The former invade native vegetation usually adversely affecting regeneration and survival of the indigenous flora and fauna. Environmental pest plants include trees, shrubs, vines, creepers, grasses, bulbs, tubers, rhizomes, and aquatic plants. Agricultural weeds threaten crop production.

Examples given of the characteristics that earn a plant "pest" status include:

competes with more desirable plants, such as crops; poisons livestock and humans (includes allergens); injures livestock; interferes with agricultural processes (harvest, etc.); taints or contaminates products; interferes with transportation, essential services, or recreational use of land and waterways; alters the habitat value of wetlands, native forests, grasslands, or other areas; and, presents aesthetically undesirable characteristics such as offensive odors. Submissions to the Committee closed in mid-September. Based on information collected, recommendations to the full State Parliament are anticipated on statewide priorities for pest plant control as well as possible cost-sharing arrangements. FMI: S.

Insect Threatens California Vineyards A minute, yellow aphidlike insect long a serious pest to European vineyards and native to the eastern U.S., has evolved into a new biotype that poses a serious threat to the prolific wine industry of northern California, according to a recent feature in CALIFORNIA AGRICULTURE. The crisis, attributed to grape phylloxera (Daktulosphaira vitifoliae [Fitch]), began in 1983 when scientists identified a new biotype of the insect. Phylloxera damages grapevines by feeding on roots, leading to steady decline; infested vines stop producing after two to three years.

Scientists at the Univ. of California who have mounted an extensive research effort report that there is no known chemical or biological control for D. vitifoliae. Pesticide applications, while shown to kill the insect in lab studies, proved ineffective when applied to vineyard soil. The nature of vineyard soils, the insect's broad distribution, and other factors appear to invalidate pesticide application as an economic and effective control.

Emergence of phylloxera-resistant rootstocks thwarted the pest for now and halted the stated "threat to devour California's North Coast wine industry." However, new evidence from Germany, where the pest is well known in vineyards, suggests that even highly resistant rootstocks may become susceptible under some circumstances.

Research will continue in California to try to learn more about phylloxera and tactics to control it.

Herbicide Resistant Maize Arrives A U.S. firm recently announced receiving a U.S. patent for fertile, transgenic corn (maize) resistant to glyphosate, a nonselective, systemic herbicide. DeKalb Genetics Corp. said use of its genetically altered seed would allow growers to apply glyphosate to control weeds and not harm the corn crop. DeKalb chairman/CEO B.P. Bickner stated that farmers could "dramatically improve their options for post-emergent weed control" by using the firm's new seed material. Bickner also said that, "We expect to introduce glyphosate-resistant corn hybrids in the spring of 1998, which would make DeKalb the first in the industry with this product."

Since the beginning of 1996, the U.S. Patent and Trademark Office has granted Dekalb nine patents, most of which relate to products with herbicide or insect resistance or to the transformation methods used to develop them, the company said.

Bt-Corn Raises Expectations and Concerns After initial field tests of newly developed transgenic maize/corn hybrids containing a gene from the bacterium Bacillus thuringiensis, research scientists at the Univ. of Wisconsin (USA) found that the plants did shrug off the economically important pest Ostrinia nubilalis (Hubner), European corn borer, but voiced concern over both potential for spreading insect resistance and loss of yield due to crop depression. According to agronomist J.G. Lauer, "The technology is truly amazing. It may well revolutionize how farmers grow corn. But I don't think farmers should 'bet the farm' on these new genetically altered corn hybrids yet." Inserting a gene into a crop hybrid often initially depresses its yield, causing yield lag, Dr. Lauer pointed out.

"To test the Bt corn, a farmer could plant 5 or 10 acres of the corn and see how it performs on the farm for at least two years before making a big investment in it," Lauer said.

Working with Lauer, entomologist J. Wedberg observed that, "We know now that we can't rely on a single strategy to control insect pests." Widespread plantings of Bt-based crops may foster development of insect populations resistant to Bt, as has happened with many other insecticides, according to Dr. Wedberg.

Widespread use of a single insecticide initially kills most insect pests, but immediately begins to select for the few individual insects which, for unusual genetic reasons, can tolerate it. When these survivors breed, they quickly multiply and form a population resistant to that insecticide.

Wedberg says the way to keep Bt-based corn effective against borers and slow development of the pest's resistance to it is to plant non-Bt hybrids on a quarter of a farm's land devoted to growing corn/maize.

Both scientists caution that, based on recent experience with other Bt-carrying crops in the U.S., this tool for protecting plants from insects should be slowly integrated into an overall crop protection approach. FMI: JGLAUER@facstaff.wisc.edu, or WEDBERG@wisplan.uwex.wisc.edu.

IPM MEDLEY --- publications and other IPM information resources

III. IPM MEDLEY general information, publications of interest, and other information and resources related to IPM Ms. IPM She is articulate. She is committed to the value and benefits of integrated pest management. She is out in the fields everyday actively promoting the IPM concept. After all, she is "Ms. IPM" and her vehicle license plates proclaim it so. The "she" in this case is M. Rayburn, an area IPM agent with the U.S. state of North Carolina's Cooperative Extension Service. Ms. Rayburn comments, "Ms. IPM is my `nom de plume' or alias. I find it offers an opportunity to explain IPM to the curious who may not know about it. It is part of my marketing effort for IPM." And an integral element of her responsibilities.

"I provide IPM training and support for county ag. agents in the area, as well as conducting educational programs (scouting schools, etc.) for farmers, crop consultants, crop scouts, agribusiness people, and the general public," says Ms. IPM. "I am also involved some in IPM research projects, working with various extension specialists." In her geographic area, "most of the farmers practice IPM to some extent, but it is the non-farm public that needs to know about it. I also provide IPM programming for Master Gardeners as part of that effort. IPM works and we need to let everyone (not just farmers) know about it," she said.

Ms. IPM's message is that IPM is "good news," a reasonable balance between crop protection practices at extreme ends of the scale. "Too often farmers are caught in the modern agricultural production system," declares Ms. IPM. "They have to produce for the market that exists in their area. They may be in a small rural area that cannot support a farmer's market. They may be geared up for large scale production of grains, soybeans, or cotton and have to meet certain market criteria and economy of scale criteria to stay in business."

"Most farmers that I know don't enjoy spraying a wide variety of chemicals. They use integrated pest management to treat only in response to a problem or anticipated problem. They use preventative, non-chemical methods when they can (crop rotation, resistant varieties, etc.). But, when a pest threatens to wipe out their crop (and their livelihood), they treat the crop to reduce the pest population below damaging levels. They have mortgage payments to make, families to feed and clothe, and children to send to college."

Before accepting the IPM position with the Extension Service Ms. Rayburn managed an IPM co-op which provided crop scouting and soil sampling services to area farmers; she had dual responsibilities as co-op manager and extension agent. She was also a fulltime grower and currently farms part-time.

Ms. IPM remarked that, "I don't claim to be an IPM `Guru,' but it is my primary job responsibility. The point I am trying to make is that we all make choices. Most growers want to farm sustainably. After all, they want to be able to continue farming and want to pass the farm on to future generations. They chose to farm rather than go into some other profession. Farming sustainably also includes making a profit so they can continue to farm next year and the years after."

"I don't know that my story is unique - after all, there are lots of people involved in IPM at different levels," Rayburn observed. True, but there may be just one who bears the sobriquet "Ms. IPM" and so wholeheartedly promotes a rational and realistic approach to crop protection. FMI: M.

U.S. Names New IPM Coordinator The U.S. Department of Agriculture has selected entomologist G.W. Cuperus as IPM Coordinator replacing B.J. Jacobson, a plant pathologist, who has completed his assignment and returned to a previously-held university position. Dr. Cuperus, a faculty member at Oklahoma State Univ. where he has been IPM Coordinator since 1992, has been actively involved in IPM-related issues and programs like water quality, sustainable agriculture, and food safety. He also serves on several national committees and the national IPM Task Force.

Cuperus will hold the national IPM coordinator position for a year.

IPM Mission Spelled Out The Univ. of California (USA) Statewide IPM Project has adopted a mission statement to guide activities and direct future thrusts. The project, established in 1980 to develop and promote the use of integrated, ecologically sound pest management programs across the state, has as its mission: to reduce the pesticide load in the environment; to increase the predictability, and thereby effectiveness, of pest control techniques; to develop pest control programs that are economically, environmentally, and socially acceptable; to marshal agencies and disciplines into integrated pest management programs; and, to increase utilization of natural pest controls. IPMporium ..... Earlier control of the "green bridge," volunteer crops and weeds that grow after fall harvest, can significantly reduce root disease incidence in spring-planted crops, increasing yields by up to 50 percent. ..... A software program, VIRTUAL PLANTS, is said to provide "new perspectives to ecologists, pathologists, and agricultural scientists," according to a review in TRENDS IN PLANT SCI., 1(1), 33, January 1996.

..... Based on recent research, timing management operations of the aquatic weed Hydrilla verticillata (L.f.) Royle to occur at "weak" points in the plant's carbohydrate production cycle could improve the level of control achieved.

..... Canadian scientists are developing a bioherbicide (native occurring pathogenic fungus) to help manage Rubus spp., plants that vigorously compete with (and often overpower) young conifers in reforestation schemes.

..... The Univ. of Florida (USA) recently began using a new "urban entomology laboratory" focused on research related to cockroaches and fleas, among other urban pests.

..... Also in Florida, during 1995 IPM scouting covered 86 percent of the State's soybean fields, 60 percent of the peanut/groundnut fields, and 42 percent of the cotton fields.

..... A research effort funded by the Australian Center for International Agriculture resulted in development of wheat varieties containing resistance to the cereal disease "barley yellow dwarf virus."

..... According to a forest plant pathologist, it is imperative to develop IPM systems which will minimize or prevent disruption of forest tree nursery operations where methyl bromide can no longer be used.

..... The 1997 International Grassland Congress scheduled for Canada will entirely devote one of its numerous "themes" to pests and IPM.

IPM RESEARCH/TECHNICAL PAPERS --- categories and topics related to IPM

II. RESEARCH REVIEW research and findings related to IPM. Vineyard Cover Crops Offer Benefits Research scientists in the U.S. state of California are experimenting with a variety of ground cover schemes in vineyards, ranging from natural (weedy) vegetation to specifically planted cover crops. Aside from improving tilth in general, covers can influence pest and natural enemy populations, writes vineyard specialist M.J. Costello. Dr. Costello and colleagues recently completed several years of studies on the effects of vineyard floor vegetation on spiders and leafhoppers. Results indicate that maintaining a ground cover can reduce the leafhopper populations in some cases.

Ground cover tactics are but one component in a broader initiative, Biologically Integrated Vineyard Systems, that encourages production systems which replace practices that are either disruptive to nontarget species, or can result in off-site problems.
