Aerial Field Tests of Five Insecticides on Western Spruce Budworm in Idaho and Montana, 1978-1980
Author: George P. Markin
Publisher:
ISBN:
Category : Aerial spraying and dusting in forestry
Languages : en
Pages : 6
Book Description
Each of five insecticides was applied at two or three application rates by helicopter to 20-ha plots. Effectiveness of each application rate against western spruce budworm (Choristoneura occidentalis Freeman) was judged by cornparing larval population reduction at I5 or 20 days after treatment against populations in untreated check plots. Performance of each insecticide was then compared with the levels of control normally obtained with two registered insecticides. carbaryl and acephate (90 + pct) usually used for western spruce budworrn control. Maximum population reduction from sulprofos (58 pct), phosmet (59 pet). and from the growth regulator BAY SIR- 8514 (58 pet), at all application rates tested was below the acceptable minimum of 90 + percent population reduction. Methomyl reduced populations 92.3 percent at 0.28 kg a.i./ha and 94.0 percent at 0.56 ke a.i./ha. Permethrin at 0.11 kg a.i.iha reduced the population by 93.9 percent. Methonyl and permethrin at these application rates appeared to be as effective as the registered insecticides acephate and carbaryl.
