摘要: 为提高现有生物农药对番茄灰霉病的防治效果,本文研究了中生菌素和纳他霉素的复配制剂对番茄灰霉病菌菌丝生长和孢子萌发的抑制作用以及田间防病效果,确定了二者复配的增效作用及适宜配比。结果表明,中生菌素和纳他霉素质量比为9:1和1:1时,复配制剂对菌丝生长的抑制作用明显,具增效作用,增效系数分别为3.6348和1.7145;二者质量比为9:1、7:3和1:1时,对孢子萌发的抑制具有增效作用,增效系数分别为1.7268、1.6335和1.5336。田间试验表明,3%中生菌素·纳他霉素可湿性粉剂(9:1)500倍稀释液防病效果最好,施药7 d后对叶片和果实上的灰霉病防效分别达到81.04%和78.48%,显著高于单一制剂的防病效果。上述结果表明,适当配比的中生菌素与纳他霉素复配制剂对番茄灰霉病的防治效果显著增强,对生物农药的田间应用具有实际指导意义。

Abstract: In order to improve the control effect of existing bio-pesticides on tomato gray mold,the inhibitory activities of mixtures containing Zhongshengmycin and Natamycin on mycelial growth and conidial germination of Botrytis cinerea were investigated,and the synergistic effect and appropriate ratio of the two pesticides were determined.The mixtures of Zhongshengmycin and Natamycin showed synergistic effect on inhibition of hyphae growth when their weight ratios were at 9:1 and 1:1,with the synergistic coefficient of 3.6348 and 1.7145,respectively.Synergistic effect was also expressed in inhibition of the conidial germination when their weight ratios were at 9:1,7:3 and 1:1,with the synergistic coefficient of 1.7268,1.6335 and 1.5336,respectively.Field experiments showed that the 500 x dilution of 3% wettable compound powder of Zhongshengmycin and Natamycin (9:1) performed good effects on tomato gray mold on leaves and fruits,with the control efficacies of 81.04% and 78.48%,respectively,significantly higher than that of individual ingredient.The above results showed that the mixture of Zhongshengmycin and Natamycin in proper proportion could effectively improve the control effect on tomato gray mold.
