Brazil reports earworms migrated to pasture
The devastating agricultural pest, the earworm (Helicoverpa armigera), has been detected on pastures in Brazil, national media report. The earworms have caused deep and widespread losses on cotton, soybeans and some maize crops in the country, leading to declared states of emergency in several states, and an emergency decree at national level (Agrow passim). The pest's latest appearance was reported in Mato Grosso state by an agriculture research entity, Fundacao Chapadao. The finding is a “major worry” as no insecticide to deal with the pest is registered for use on pastures. Fundacao is studying its behaviour to ascertain whether or not it is similar to that on other crops, aiding the search for a reliable product for potential registration. The discovery was made some three weeks ago, and damage is being "calculated".
