DPR Approves Special Local Need for Brigade for Fuller Rose Beetle
DPR issued a special local need effective September 9, 2013 that allows the use of Brigade WSB on citrus trunks at the 5 lb product (0.5 lb ai/acre) rate for Fuller rose beetle. The SLN allows two treatments of 5 lbs applied 12-16 weeks apart OR four treatments of 2.5 lbs applied 6-8 weeks apart. The SLN allows the use of either a hand wand sprayer or shielded sprayer to apply the treatment to the lower 18 inches of skirt-pruned tree trunks. This SLN provides a higher rate and an additional method of application - which should improve control of Fuller rose beetle. Dr. Joseph Morse and Dr. Beth Grafton-Cardwell are conducting field trials to determine the best combination of treatments (skirt pruning, trunk treatments, foliar treatments) to prevent Fuller rose beetle from laying eggs under the calyx of fruit. Korea is allowing Methyl Bromide fumigation this year, but is definitely not allowing it next year. So it is important to continue to treat for Fuller rose beetle this season to drive the beetle populations down and make control easier next year.
