The tropical mite on cotton Polwhaqolarswnemus latus (Banks, 1904) (Acari: Tarsonemidae) and test of chemical control

Chemical control of the tropical mite was evaluated by means of a field test conducted in Tiete, State of São Paulo, Brazil. Seven treatments with four replicates each were applied to plots of 150m². Treatments and their respective active ingredients were as follows: A) check; B) triazophos, 300g; C) triazophos, 150g + pheromones (multimethyl alkenols), 4.77g; D) propargite, 1080g; E) abamectin, 6g + pheromones (multimethyl alkenols), 6.67g; F) profenophos, 400g; G) sulfur, 3000g. Best results were obtained with treatment B (triazophos), followed by G (sulfur) and the two mixtures with pheromones (C and E) (triazophos plus multimethyl alkenols and abamectin plus multimethyl alkenols) (tables 2, 3 and 4). Predador mites were considered.
