| 摘 要： | 为减轻豇豆炭疽病发生危害,减少化学农药用量、残留和环境污染,采用测报调查、随机区组设计和统计分析等方法,开展了生物农药几丁聚糖、生化复配制剂咪鲜.几丁糖和化学农药苯醚甲环唑、噻呋酰胺防治豇豆炭疽病农药田间药效试验。结果表明:在温室大棚秋季豇豆炭疽病发生较重情况下,每hm2用2%几丁聚糖AS2250g、46%咪鲜.几丁糖EW 450g、10%苯醚甲环唑WG900g(对照药剂)和24%噻呋酰胺SC360mL,5-8天施药1次,连续施用3次,药后7、14和20天,防治效果均在83%、78%和73%以上,且4种药剂防治效果差异不显著,该4种药剂尤其是几丁聚糖和咪鲜.几丁糖不仅可以作为防治炭疽病的理想药剂,而且可以作为现代农业示范区、无公害农产品、绿色农产品和有机农产品的理想药剂,确保现代农业、绿色农业、有机农业和生态农业发展需要。

Control Effect of Four Kinds of Agents on Greenhouse Autumn Cowpea Anthracnose |
| |
| Abstract: | In order to reducing the occurrence and damage of cowpea anthracnose, decreasing the chemical pesticide consumption, residue and environmental pollution, the methods of forecasting, randomized block design and statistical analysis were used to the field efficacy trials, which conducted of the control effect of cowpea anthracnose by using bio-pesticide : Chitosan,biochemical compound preparation Prochloraz-Chitosan,chemical pesticides Difenoconazole and Thifluzamide. The results showed that after applying 2% Chitosan AS 2250g,46%Prochloraz-Chitosan EW 450g,10%Difenoconazole WG900g(Control agent)and 24%Thifluzamide SC360mL per hm2 per 5-8 days period, and continuous applied 3 times during serious morbidity autumn in greenhouse, the control effects were all over 83%, 78% and 73%, respectively, at 7 days, 14 days and 20 days after treatment.The control effects between 4 kinds of agents were no significant difference. These results indicated the 4 kinds of agents, especially that Chitosan and Prochloraz-Chitosan were ideal bio-pesticides, which could not only be used for controlling tomato virus diseases, but also realize modern, pollution-free, green and organic agricultural production. |
