A Weisu Jinggangmycin mixed with the effect of the control of rice sheath blight
  
  
Through the weak, by rain impact. Long-term use of insect resistant and insect-resistant spectrum is relatively narrow issues. A Weisu by avermectin compound is made with the new Bt insecticide, Bt both abamectin and the dual role of insects in the Arab resistance to the avermectin, so as to achieve mutually added to enhance the efficacy of the role, not only increased its pest spectrum, but also quick to make up for poor performance after Bt application deficiencies. In addition,Pandora Gioielli Roma, the compound can also be effective after a delay of pest resistance to Bt insecticides, anti-extension of validity period,Moncler Türkiye, Lepidoptera pests 1015d, mites 3045d. To humans and animals, predators, animal and crop itself is very safe, in crops, water, soil, air, no residue, has a very considerable economic, social and ecological benefits. In the control of rice sheath blight, in order to increase the control effect, usually two kinds of pesticides. Therefore, to study Avi - after the Soviet Union and Jinggangmycin mix for rice sheath blight control effect, the pharmaceutical powder mix with Jinggangmycin conducted field control efficacy trials. 1 Materials and methods 1.1 Basic Test selection in Baoying County Town of rice fields for Liu, Hong Guangling test japonica varieties,moncler jacken schweiz, Previous Crops of wheat, rice growing in general. WP 1.2 for the test by the Pharmacy A Weisu Dongbao Agrochemical Co.,Moncler Jackets, Ltd. Yangzhou production; 20% WP Jinggangmycin produced by Zhejiang Qianjiang Biochemical Co., Ltd.. 1.3 methods of handling and testing a total of four treatments: ① A Weisu 100g +20 Author Zhang Yadong (1972 A), male, Jiangsu Baoying people, agronomists, pest forecasting and control in pain research. Received 2005.12-16% Jinggangmycin 1125g/hm; ② A Weisu 1500g/hm: ③ 20% Jinggangmycin 1125g/hmz; ④ blank control. Residential area of ??66.7m, repeated three times for each treatment, medication time was August 13, 2005, drug use equipment for the sprayer, water 750kg/hin mixture evenly spray, spraying when the weather is sunny. 1.4 Content and method of drug investigation before the investigation of the area medicine 15d incidence, 50 points for each survey area, recording the number of diseased plants, severity, disease index calculation. 2 Results and analysis of survey results 15d after treatment (Table 1) shows that A Weisu Jinggangmycin 100 different powder 75g + 20% of the maximum effect of disease prevention, anti-efficiency of 85.70%; alone 20% Jinggangmycin the effect powder 75g,ghd piastra, followed by disease prevention, anti-efficiency of 80.35%. Table 1 Jinggangmycin mix different pesticides and the effect of control sheath blight _ ① a - T Wan ------ ■ ----- clever one (4.6432.21 a ③ 2.433.8580.35 : Q wire: wire two 3 Discussion and Summary of rice sheath blight is an important Jiangsu Baoying disease, resulting in annual rice production, caused great harm. Jinggangmycin China in the 1970s developed the first one microbial pesticides, the Streptomyces Jinggangmycin variant metabolism, with extremely high levels, the use of low-dose and low-cost, etc., has become the most widely used area, the lowest-cost pollution-free pesticides. but long-term use of some insects have become resistant, so that anti-down effect, so look for alternatives or mix with other pesticides, is becoming increasingly important minutes right column studies have shown that 30% of the rice sheath blight Armure Ec can achieve the desired control effect. Zhu Long powder that has 9708 plus Bacillus surfactant wax powder on rice sheath blight control effect is good, and long duration, is a good alternative varieties Jinggangmycin agent Xu Hui hatch after tests showed that 12.5% ??use WP diniconazole WP can achieve better control of rice disease control effect. The results show that E Weisu mixed with Jinggangmycin after Jinggangmycin control sheath blight control effect is not obvious, both are in the 80% control efficiency above, but with Jinggangmycin and compared with the control effect increased slightly, an increase of about 5%.
