Effect of Neem Products and Synthetic Insecticides against Sucking Insect Pests of Cauliflower under Field Conditions
No full text :A field study was carried out during 2015 at Muhammad Bachal farm at Bakrani District Larkana. Four treatments with three replications were applied. The treatments were: T1=Chemical control (Diamond 20SP), T2=Neem oil, T3= Neem kernel, T4= Untreated (Control). Two insect pests were found infesting Cauliflower including white fliesand thrips. Pre-treatment- and post-treatment observations were recorded. The results revealed that against thrips, the first spray of chemical control (Diamond) showed highest reduction percent (50.61%) followed by neem oil (43.33%), neem kernel (40.42%), and lowest for untreated control (10.31%); while in the second spray also, chemical control (Diamond) showed highest effect against thrips (58.51%); followed by neem oil (57.88%), neem kernel (52.43%) and least by untreated plot (14.77%). Against white flies chemical control (Diamond) showed highest effect (82.89%) as observed during 1st spray, followed by neem oil (72.47%), neem kernel (72.68%), and untreated control (5.12%), while after second spray also chemical control (Diamond) showed highest reduction percent (85.53%) followed by neem oil (74.34%), neem kernel (72.26%), and the lowest was resulted by untreated control (4.11%). Chemical control (Diamond) showed its superiority in effect to combat sucking insect pests studied in cauliflower, followed by neem oil, neem kernel, and untreated control remained the least.</jats:p
Effect of Natural Enemy (Chrysoperla carnea Stephens) against Sucking Insect Pests of Okra
No full textAn experiment effect of natural enemy (Chrysoperla carnea Stephens.) against sucking insect pests of Okra was carried out at Latif Farm, Sindh Agriculture University, Tando Jam during 2014.The results showed that overall maximum mean population of jassids (1009.5 ± 78.12/plant) was recorded in pre-treatment treated plot followed by thrips (706.17 ± 34.26/plant), mites (572.5± 33.00/plant) and whiteflies (209.83 ± 19.76/plant) respectively. Whereas, the overall maximum mean population of jassids (1322.44 ± 8.6/plant6) was recorded in pre-treatment control plot, followed by thrips (828.05 ± 6.77/plant), mites (640.55 ± 5.95/plant) and whiteflies (267.38 ± 4.74/plant) respectively. However, the overall maximum mean of jassids (434.27 ± 4.91/plant) were recorded in post-treatment control plot, followed by thrips (278.11 ± 3.93/plant), mites (134.11 ± 2.63/plant) and whiteflies (18.83 ± 0.99/plant), respectively. The results further revealed that the statistical analysis of data through paired T-test between treated and control plot of jassids, whiteflies, thrips and mites showed significantly different at (P<0.05) level. Whereas, the statistical analysis of data through paired T-test between pre-treatment and post-treatment of jassids, whiteflies, thrips and mites also showed significantly different at (P <0.05) level.</jats:p
