PEACH, EVALUATION OF FOLIAR INSECTICIDES TO CONTROL PLUM
CURCULIO, 2000: Plots were set up to compare the effectiveness of different treatments
using Actara and Asana in the control of plum curculio (PC) in one commercial orchard in Wayne
Co. Treatments were arranged randomly and applied in single-tree plots that were replicated 4
times. Treatments were applied using a hand-held gun from a truck-mounted nursery sprayer
(Rears Nifty-Pul-Tank) operating at 300 psi, and delivering 5 gal per tree in a mature (10 yr-old)
planting of 'Baby Gold' peaches at Cherry Lawn Fams in Sodus, N.Y. Treatments and rates
applied were: Actara 25WG at 5.5 oz and 4.5 oz formulation per acre, and Asana 0.66EC at 8 oz
per acre, plus an untreated control. All treatments were applied at pink (April 25) and petal fall,
shucks on (May 11).
Fruit damage was assessed on June 27 during the fruit thinning period (1-inch fruit size).
Counts were taken by sampling 100 random fruits from each tree and inspecting each for plum
curculio oviposition or damage that could have been caused by catfacing insects. The data were
transformed using arc-sine square root and analyzed using ANOVA; treatment means were
separated with Fisher's Protected LSD at the P = 0.05 level. Results are given in Table 1.
