BULLETIN NO: MGR-97-029 TO: All Reinsured Companies All Risk Management Field Offices FSA Headquarters, Program Delivery & Field Operations FROM: Kenneth D. Ackerman Administrator SUBJECT: Corn Rootworm Integrated Pest Management (IPM) Demonstration Project BACKGROUND: Risk Management Agency (RMA) received a request to provide insurance protection to corn producers participating in the Agricultural Research Service's (ARS) Integrated Pest Management (IPM) Area wide Corn Rootworm Project. This project is funded by the Department of Agriculture and coordinated by the ARS Corn Rootworm Laboratory in Brookings, South Dakota. It involves land-grant Universities in Illinois, Indiana, Iowa, and Kansas, and is intended to demonstrate the effectiveness of IPM procedures to control corn rootworm. Corn rootworm refers to four Diabrotica species commonly named the Northern, Western, Southwestern, and Southern corn rootworm. The larvae of these species damage corn throughout the corn belt by feeding on roots. Eggs are laid by adults in the soil. The eggs hatch the following spring and the larvae feed on roots of young corn plants, thus reducing nutrient and water uptake. Damage is most severe when the corn is stressed, but yield loss is minimal when soil moisture and fertility are adequate. Analysis of the data submitted by the ARS indicates that the risk of significant damage from corn rootworm in a tightly controlled IPM demonstration project such as this is small. This is due to five factors: 1) the demonstration sites will be scouted weekly from adult emergence through its egg laying stage; 2) the insecticides, SLAM or COMPELL, will be applied as necessary to achieve needed reductions in egg laying; 3) the demonstration areas will be resprayed as necessary; 4) where scouting indicates insufficient control, cooperators will be advised to utilize a soil insecticide treatment or to rotate to a nonsusceptible crop the following year; and 5) multi-year data from ARS supervised trials in South Dakota and Texas indicate control of corn rootworm is equal to current practices. Also, the risk of losses from other pests will be reduced because scouts will identify other problems so that growers can take timely action. RMA is supporting this ARS demonstration project by assuring cooperating farmers that their crop insurance coverage will apply to acreage in the IPM demonstration sites, which are located in Iroquois County, Illinois; Benton County, Indiana; Clinton County, Iowa; Republic County, Kansas; Brookings County, South Dakota; and Bell County, Texas. The demonstration project utilizes semiochemical based insecticides, which prevent damage to beneficial insects and reduce human and environmental risks. Two insecticide products will be used on acreage when adult populations exceed a specified threshold, as measured by IPM scouting. This adult control concept will reduce egg laying and preclude the need to use soil insecticides at planting the following year. If weekly IPM scouting reports indicate that adult rootworm suppression was inadequate, cooperating farmers will be advised not to plant corn (this would not entitle farmers to the 25 percent alternative crop prevented planting payment) or to use a soil insecticide treatment for corn rootworm control. ACTION: For policyholders participating in the ARS Corn Rootworm Demonstration project, in the above identified counties who insure corn, hybrid corn seed, popcorn, or sweetcorn, reinsured companies are authorized to issue agreements in writing for the 1998 through 2002 crop years that provide the following: "Recognized good farming practices" will include adult corn rootworm control with semiochemical based insecticides recommended as part of the United States Department of Agriculture/Agricultural Research Service (USDA/ARS) sponsored Area wide Corn Rootworm Integrated Pest Management (IPM) Demonstration Project. Whenever IPM scouting reports indicate that adult rootworm suppression has been inadequate and you are advised not to plant corn, the affected acreage will not be considered prevented from planting. No prevented planting indemnity for corn, hybrid seed corn, popcorn or sweet corn will be paid on that acreage.
