On 26 Apr prior to the initiation ERR_HeadC=ERR_HeadD=ERR_HeadC=ERR_HeadD/HeadC increases blossom drop. High populations of mite can also cause of treatments, 1.58 ± 3.76 mites per leaf was observed. Data were fruit russeting, resulting in loss of yield and quality. This trial was analyzed using ANOVA and differences among treatment means on ERR_Extract3=ERR_HeadA=ERR_Extract1=ERR_HeadA conducted at the Southwest Florida Research and Education Center each sampling date were determined using least significant difference in Immokalee Florida. The greenhouse-raised pepper plants were test (P = 0.05). transplanted in the field on 4 March at 18 inch spacing on three beds All treatments on all sample dates significantly reduced the number covered with black polyethylene film mulch. Plots consisting of 10 of broad mites and their eggs when compared with the untreated plants bordered by a 6 foot buffer were assigned to eight treatments check except BoteGHA 32 oz treatment by itself for broad mites and and untreated check in RCB design with four replications. Four JMS Stylet Oil/M-pede rotation for eggs on 10 May (Table  1). On applications at 1  wk intervals were made using a high clearance the same date, broad mite numbers in these two treatments were sig- sprayer operating at 180 psi and 2.3 mph (Table  1). Spray was nificantly more than in the treatments of Agrimek, Torac, and Portal delivered through two vertical booms fitted with three yellow Albuz treatments all applied with Induce. On the other sampling dates, ATR 80 hollow cone nozzles on each drop discharging 10 gpa there were no significant differences among treatments for broad each for a total volume of 60 gpa. Populations of broad mite were mites or their eggs (Table  1). No phytotoxic effects were observed monitored on 3, 10, 17, and 24 May by sampling eight terminal in any treatments. - Table 1.
