Family farmers and the diamondback moth: recognition, control, and difficulties

Abstract

Plutella xylostella (diamondback moth) is the main pest that attacks kale (Brassica oleracea L.) and, when poorly controlled, can compromise the entire production. The objective of this work was to carry out a diagnosis of P. xylostella control practices adopted by family farmers who grow cabbage in the municipalities of Lucas do Rio Verde, Sorriso and Sinop, aiming to generate knowledge that increases the consumption of vegetables, as foods that promote health. These municipalities together produced 143 tons of cabbage, almost entirely produced by family farmers. It were selected 42 producers who answered the proposed questionnaire and it was found that the most used method of controlling is chemical, followed by biological. Regarding chemical control, it occurs with the use of 28 commercial products, of which only 10 are registered, and this activity exposes producers to direct contact with pesticides during the application of the products. Allied to this, the EPIs are not used properly, although they know its importance. Alternative controls such as the use of botanical extracts and / or alternative components are known, but little used and there are several difficulties reported to control the moth.
