Abstract
During a period from 1973 to 1975, 90 commercial potato fields in southern Idaho were sampled to measure the relationship between spread of potato leaf roll virus (PLRV) and numbers of Myzus persicae (Sulzer). From these data, mathematical models were constructed to predict whether or not economic levels of PLRV would be present at harvest. Simple word models were prepared for growers’ use. The model for southwestern Idaho stated that control measures should be initiated when more than 40 green peach aphids were found/50 leaf samples in 2 consecutive weeks before Aug. 1. In southcentral Idaho, aphids should be controlled when more than 10 were found/50 leaf samples in 2 consecutive weeks before Aug. 1.This publication has 1 reference indexed in Scilit:
