Abstract

This research is conducted to find out the effect of the treatment involving the application of bio agent Trichoderma Sp and synthetic insecticide containing active substances of Metomil, Beta siflutrin 25%to the population of cotton leafworm and its attack intensity to the number and weight of edamame soybean’s seed. This research is conducted for 3 months from Januari 2019 to March 2019. This research is conducted at the edamame soybean field of the farmers at Dukuh Mencek village, Sukorambi Sub-District, Jember Regency. Thisresearch employs observation survey method in between the two treatments, namely the application of bioagent Trichoderma Spbio-pesticide and sythetic pesticide containing active substance Metomil, andBeta siflutrin 25% with the collection of 50 samples per plot/treatment. This research is analyzed using SPSS 15.00. The conclusion of this research reveals that the population of cotton leafworm differs significantly. The number of population at the treatment using Trichoderma Sp is recorded 0,98 per sample plant compared to 1,44 per sample plant at the control/sythetic group. The intensity of the attck of the cotton leafworm. The attack intensity at the treatment using Trichoderma Sp is recorded 17,16%as compared to 23,07 at the control/sythetic group. Regarding the number of seeds,there is no significant difference as shown by the average number of 20,88 seeds per plant at the treatment using Trichoderma Sp as compared to 29,76 per sample plant at the control/sythetic group. Similarly, the weight of the seeds shows no no significant difference demosntrated by the average number of 41,66 gr per sample plant at the treatment using Trichoderma Sp as compared to 51,72 gr per sample plant at the control/sythetic group, respectively.
