Embodiment 1

[0043] Example 1: Indoor toxicity determination of thiophanate-methyl, Zhongshengmycin, and metalaxyl against P. infestans. The test objects were collected from potato seed tubers and cultivated separately.

[0044] Table 1: Laboratory toxicity test results of thiophanate-methyl, Zhongshengmycin, and metalaxyl against P. infestans.

[0045]

[0046] It can be seen from Table 1 that the mixing ratio of thiophanate-methyl, zhongshengmycin and mefenaxyl is between 1-80:1-40:1-40, which has obvious synergistic effect on P. infestans function, the co-toxicity coefficient is above 140, especially the 42:1:12 ratio has the largest co-toxicity coefficient. The mixing ratio of thiophanate-methyl and Zhongshengmycin is 42:1, and the co-toxicity coefficient is 48.9, showing an additive effect. The mixing ratio of Zhongshengmycin and Zhongshengmycin is 1:12, and the co-toxicity coefficient is 14.2, showing an additive effect. The mixing ratio of Zhongshengmycin and Zhongshengmycin i...

[0051] It can be seen from Table 2 that the mixing ratio of thiophanate-methyl, Zhongshengmycin and mefenaxyl is between 1-80:1-40:1-40, which has obvious synergistic effect on potato black mole function, the co-toxicity coefficient is above 120, especially the 42:1:12 ratio has the largest co-toxicity coefficient. The mixing ratio of thiophanate-methyl and Zhongshengmycin is 42:1, and the co-toxicity coefficient is 70.6, showing an additive effect. The mixing ratio of Zhongshengmycin and Zhongshengmycin is 1:12, and the co-toxicity coefficient is 130.1, showing an additive effect. The mixing r...

Abstract

The present invention discloses a pesticide composition for seed potato treatment. The pesticide composition comprises three active ingredients of thiophanate-methyl, Zhongshengmycin and metalaxyl-M, the weight ratio of thiophanate-methyl to Zhongshengmycin to metalaxyl-M is 1-80: 1-40: 1-40; by use of the pesticide composition for the potato seed potato treatment, potato planting disease resistance is enhanced, potato resistance is induced, and potato production is increased.

Description

technical field [0001] The invention belongs to the field of agricultural planting, and in particular relates to a pesticide composition for treating potato seeds. Background technique [0002] During the potato cultivation process, the leaves shrunk and curled, the leaf color was uneven, the stems were short and thin, the tubers were deformed and cracked, and the yield decreased year by year, which indicated that the potatoes had "degenerated". Seed potato "degeneration" is caused by virus infection and its accumulation in tubers, and it is also the main reason for the decrease in yield and the deterioration of commercial properties. Virus-free seed potatoes refer to the seed potatoes with little or a small amount of virus infection obtained after a series of technical measures to remove the virus in the potato tubers. It has the advantages of early maturity, high yield, and good quality. Virus-free seed potatoes are divided into original seed potatoes, original seed potat...
