为更有效地防治烟草青枯病,从无机农药、有机农药、植物性农药和微生物农药中筛选出10种进行防治烟草青枯病的田间试验。结果表明,1B°石硫合剂喷雾防治效果达85.2%.100%;植物性农药菌毒力杀、菌病一针净、博农溶液防治效果达63%-93.36%;微生物农药防治效果达66.7%。用10种药剂处理移栽后的烟苗,青枯病的发病时间比对照推迟15.20天。
In order to prevent and control tobacco bacterial wilt effectively, 10 kinds of field experiments on tobacco bacterial wilt were screened from inorganic pesticides, organic pesticides, plant-based pesticides and microbial pesticides. The results showed that the control effect of 1B ° stone sulfur mixture spraying was 85.2% .100%; the phytochemical pesticide was virulently killed, the pathogen was purely needle, the antifungal activity of Beonong reached 63% -93.36%; the control effect of microbial pesticide reached 66.7% %. With 10 kinds of agents to deal with the transplanting of tobacco seedlings, the onset of bacterial wilt delayed 15.20 days than the control.
