Berries Peasize EL 31 is a critical time to asses the level of light brown apple moth (LBAM) in your vineyard.
LBAM insecticides Avatar®, Entrust®, Proclaim® & Success® all have a with-holding period of peasize (EL 31). In most vineyards berries have grown past Peasize 7mm (EL 31). For Chardonnay, Shiraz, Merlot and Sangiovese in the warmer parts of McLaren Vale, only the biological insecticide BT’s can be used now.
Vineyards in the Adelaide Hills are 2 weeks away from the Berries Peasize cut off.
