Cabbage Maggot Control, 1979

Abstract

Abstract 'Market Victory' cabbage was transplanted to the field on Jun 8. Each treatment consisted of a 20-ft row and was replicated 4 times in a randomized complete block design. The soil type was a fine sandy loam. Insecticide applications were based on 36-in. row spacing. Furrow treatments of Temik were placed down immediately before transplanting with the use of a Gandy applicator, (Line Tender model). Sprays were applied with a 3 gallon stainless steel backpack sprayer. Applications of Amaze, UC 21865, and Diazinon were made on Jun 25. On Jul 7 Amaze and Diazinon were applied, one other application of Diazinon was made on Jul 26. Evaluations were made on Aug 8 by removing 10 roots/treatment/replication, taking a 10 cm diameter core of soil around the root. The roots and soil were rinsed through a screen to separate pupae and larvae from the soil. The number of cabbage maggot tunnels, number of larvae and pupae were recorded for each root.</jats:p
