大蒜原液对芒果花期主要害虫防治试验

Control of Mango Major Insects in Blossom with Garlic

用大蒜原液(A)、原液稀释5倍(B)、原液稀释10倍(C)、原液稀释15倍(D)对芒果花期主要害虫进行防治。试验结果表明:各处理,CK2防治扁喙叶蝉效果与CK1相比,在1%水平上差异达极显著(P<0.01)。处理A,B防治花蕾蛆的效果与CK1相比,在5%水平上差异显著(P<0.05)。处理B防治褐蓟马的效果与CK1相比,在1%水平上差异达极显著(P<0.01);处理B,C,D防治茶黄蓟马的效果与CK1相比,在1%水平上差异达极显著(P<0.01);处理A,CK2防治茶黄蓟马效果与CK1相比,在5%水平上差异显著(P<0.05)。

Garlic liquid was diluted to 5, 10 and 15 times, were sprayed to mango tree at blossom stage. The results showed that the control effect of all treatments and CK2 for Idioscopus incertus （ Baker）, treatments B for Scirtothrips mangiferae and treatment B, C, D for Scirtothips dorsalis were very significant compared with CK1 at 1% significance level. While treatment A and B for Contarinia cirri （Barnes）, treatment A and CK2 for Scirtothips dorsalis were significant compared with CKl at 5% significance level as well.
