Evaluation of Insecticidal Control of Hessian Fly in Wheat, 1989


 This test was conducted in dryland wheat at Sidi El Aydi, Morocco, during the 1988-89 growing season. The Hessian fly susceptible variety, Nesma, was planted in a vertic calcixeroll soil (66% clay, 25% silt, 9% sand, and 1.87% organic matter). Treatments were arranged in a randomized complete block design with 4 replicates. The plots were 1.5 m wide (six rows) x 11 m long and separated by 0.5 m bare ground. Granular insecticides were applied in-furrow with the seed at planting (7 Dec 1988) to control the first generation HF. Foliar applications of insecticide sprays were made to control the second generation HF. They were applied with a hand operated backpack sprayer delivering 200 liter/ha the first week of Feb when the 2nd generation flight had just started. In Mar, 20 plants were collected from the outside rows of each plot and examined in the laboratory for 1st and 2nd generation Hessian fly and for sawfly. Minimum air temperatures for Dec through Mar averaged 4.5 to 6.0°C and maximum air temperatures averaged 18.4 to 22.8°C. A total of 132 mm of rain fell prior to planting, but after planting there were only 5 rainfall events during the period greater than 10 mm, 7 Jan, 25 Feb, and 17, 18, and 27 Mar for a total accumulation for the period of 147 mm.
