abstract
The field evaluation of such synthetic pesticides (Acetamiprid 19% weightable water (WW), Lambda 25% WW, Colarphipare 32% WW, Lambda 2.5% WW, and Abamectin 1.3% WW for their effectiveness on okra crops against Jassid Amrasca biguttula biguttula (Ishida) was performed during 2015 and observations were reported after 24 hours, 48 hours, 7 hours against the target insect pests. The pre-treatment count of jassid on okra was non-significant different from pesticide effectiveness (P>0.05). In contrast, the measured efficacy of different jassid insecticides, Amrasca biguttula biguttula (Ishida), was significantly different from pesticide toxicity (P<0.01). The observations were noted that both insecticides demonstrated their highest effectiveness after 7 days of spray. Acetamiprid 19% weightable water (WW) was more successful in combating target insect pests compared to other pesticides that developed 70.53 and 74.03% field effectiveness against jassid, Amrasca biguttula biguttula (Ishida) after 7 days of 1st and 2nd spray, respectively. Abamectin 1.3% WW, was moderately successful that developed 59.16 and 55.36% field efficacy against jassid, Amrasca biguttula biguttula (Ishida) after 7 days of 1st 2nd spray, respectively. Colarphipare, 32% WW, was also moderately effective, yielding field effectiveness after 7 days of 1^st and 2^nd spray, 53.61 and 46.85 percent against jassid, Amrasca biguttula biguttula (Ishida). Acetamiprid, 19% WW, demonstrated higher effectiveness against jassid, Amrasca biguttula biguttula (Ishida), led by Colarphipare 32% WW and Abamectin 1.3% WW, while Lambda 25% WW and Lambda 2.5% WW were less successful.
