采用Horsfall方法,以植物提取物Ts-39与嘧霉胺不同配比混剂对番茄灰霉病菌的联合毒力进行了研究,两种单剂不同配比包括10∶0、9∶1、8∶2、7∶3、6∶4、5∶5、4∶6、3∶7、2∶8、1∶9、0∶10,其中大部分比例增效比值在1以上,8∶2的增效比值最大达到了1.57。将不同比例的混剂在五叶期番茄幼苗上进行了进一步验证,结果表明提取物Ts-39与嘧霉胺不同配比的混剂在番茄幼苗上有增效作用,而且8∶2为11个配比混剂中的最佳配比,增效比值达到1.7,可以作为今后研究和开发的对象。
The Horsfall method was used to study the combined virulence of Botrytis cinerea and Botrytis cinerea Ts-39 mixed with pyrimethanil in different proportions including 10: 0, 9: 1, 8 : 2, 7: 3, 6:4, 5:5, 4: 6, 3: 7, 2: 8, 1: 9, 0:10, most of which are above 1, 8: 2 Efficiency ratio up to 1.57. The results showed that the mixture with different proportions of extracts Ts-39 and pyrimethanil had synergistic effect on tomato seedlings and the ratio of 8:2 was 11 A mixture of the best ratio, synergism ratio of 1.7, can be used as the future research and development of the object.
