BROWN MARMORATED STINK BUG CONTROL COMPARING BELAY, DANITOL, AND VENOM ON PEACH, 2012

Injury caused by stink bugs and TPB is collectively called catfacing injury. Treatments were applied every 10 days (31 May, 11, 21 Jun, 2, 12, 23 Jul, 1, 9, 17 Aug) to 16-year-old ‘Encore’ peach trees after BMSB activity increased in the orchard. Experimental treatments were applied to single tree plots replicated four times in a RCB using a Rears airblast sprayer (28” fan, 180 psi) calibrated to deliver 100 gpa and pulled through the orchard at 2.6 mph. Trees are spaced 25 x 20 ft. and sprayed season-long for disease management. Early-season BMSB pressure was low due to small overwintering populations but BMSB density increased rapidly and was economically damaging by late-season. BMSB was the predominant catfacing insect season long. Catfacing injury was scored at harvest on 22 Aug, by assessing 25 fruit per tree (100 per treatment). Severity of injury (i.e. average number of feeding sites per fruit) and the average number of fruit injured per experimental unit were calculated. Severity data was log transformed (log(x+1)) and percent damage data were asin(sqrt(X)) transformed before analysis with ANOVA. Where appropriate, means were separated using Tukey’s HSD at P ≤ 0.05. At harvest, all treatments were significantly different than the control for severity of injury and percent damage. There was no significant effect of rates for Belay (Table 1). This research was supported by industry gifts of pesticide and/or research funding. Table 1.
