The Effect and Benefit of Rice Chilo suppressalis Walker Chemical Control Test of Chlorantraniliprole etc.

In this paper, the first generation and second generation of Chilo suppressalis Walker were conducted as the test objects to investigate control of a new pesticide(chlorantraniliprole) with preparation of chlorantraniliprole 20% SC,abamectin 1.8% EC and chlorpyrifos 40% EC to Chilo suppressalis Walker. The results showed that chlorantraniliprole 20% SC, abamectin 1.8% EC and chlorpyrifos40% EC had effective control to Chilo suppressalis Walker for its excellent control efficacy and long persistence period. Seedling protection efficacies were between84.2%-100%, 90.1% and 92.1%, and insecticidal efficacies were between 84.6%-100%,90.7% and 93.8% 36 days after application of chlorantraniliprole 20% SC in treatments with abamectin 1.8% EC and chlorpyrifos 40% EC for first generation Chilo suppressalis Walker control. The dead panicles were between 0.2%-1.4%, 0.8%and 0.7%, pest plant rate control in 0.4%-2.2%, 1.1% and 0.9%, and the rates of damaged rice plants were between 82.4%-97.6%, 90.2%-91.2% and 91.4%-92.8%,30 days after application of chlorantraniliprole 20% SC, abamectin 1.8% EC and chlorpyrifos 40% EC for the second generation Chilo suppressalis Walker control. It can effectively protect seedlings, protect spike, increase grain number and grain weight, which promoting the increase production income effect. The real estate increased by 9.7%-12.3%, 10.9% and 11.2% than water treatment(CK) with a very significant level, while the incomes were higher than 1 719.19-1 998.22, 1 956.52 and 2 057.83 yuan.

Application Effect of Pesticide Synergist‘Jijian' on Wheat Stripe Rust

The aim of this study is to clarify the application effect of pesticide decrement synergist ＇ Jijian＇ on wheal stripe lUSt. Sampling investigation, randomized block design and statistic analysis were carried out to find out the field efficacy of adding ＇ Jijian＇ to triadimefon WP and propiconazole EC on controlling wheat stripe rust. The results showed that during the epidemic period of stripe rust, the control effects on the 7^th and the 19^th d reached more than 93% and 100% , respectively, by the application of 15% triadimefon WP of 1 200 g/hm^2 and 25% propiconazole EC of 600 mlhm^2 , respectively for 2 times ; when 15% triadimefon WP of 840 g/hm^2 ＋ ＇ Jijian＇ of 225 g/hm^2 or 25 % propiconazole EC of 420 mlhm^2 ＋ ＇ Jijian＇ of 225 g/hm^2 were applied （ adding ＇ Jijian＇ and reducing the dosage of the 2 pesticides by 30% ） , the control effect on the 7^th d was 89.4% and 91.7% , respectively, while the control effect on the 19a＇ d was 99.8 - 100% ; when 15% triadimefon WP of 720 - 600 g/hm^2 ＋ ＇ Jijian＇ of 225 g/hm^2 or 25% propiconazole EC 360 - 300 mlhm^2 ＋ ＇ Jijian＇ of 225 g/hm^2 were applied （ adding ＇ Jijian＇ and reducing the dosage of the 2 pesticides by 40% - 50% ） , the control effect on the 7a＇ day reached more than 78.0% , while the control effect on the 19^th day was 97.7% - 99.8%. There was no significant difference on the control effect at the 7^th d between the treatments using the 2 pesticides alone and the treatments adding ＇ Jijian＇ and reducing the dosage of the 2 pesticides by 30%, but all had significant differences from the treatments adding ＇ Jijian＇ and reducing the dosage of the 2 pesticides by40% -50%. There was no significant difference on the control effect of the 19^th d among different treatments. Therefore, if the disease is not serious, the application of ＇ Jijian＇ can reduce the application amounts of pesticides by 40% -50%, that is, 15% triadimefon WP of 720 -600 g/hm^2 ＋ ＇ Jijian＇ of 225 g/hm^2 or 25 % propiconazole EC of 360- 300 ml/hm^2 ＋ ＇ Jijian＇ of 225 g/hm^2, which is helpful to reduce the pesticide application amounts and pesticide residue pollution, and save the control costs.
