It is reported that the allicin and tebuconazole compound seed treatment agent developed for rice seedling disease is superior to the seed treatment agent of rice bacteriocin and azoxystrobin as the main active ingredients at home and abroad. And the cost is low, which has a promoting effect on rice seed germination; at the same time, it can effectively overcome the resistance of rice seedling pathogen to carbendazim and prochloraz.
According to reports, since the mid-1990s adopted since prochloraz Soaking control of rice seedlings evil disease, the Ministry of Agriculture so far registered pesticide test control agents rice Bakanae 86% of prochloraz or compounded agents, accounting for Rice evil The absolute status of the disease control agent. However, long-term single use of prochlorazamines to control rice seedling disease, pathogenic bacteria have obvious resistance to prochloraz, resulting in the inoculation of prochloraz can not effectively prevent the spread and spread of mite disease, causing huge Loss.
The application of tebuconazole and allicin as main active ingredients in the preparation of rice soaking agents can effectively overcome the resistance of rice seedling pathogens to carbendazim and prochloraz, and the combination of tebuconazole and allicin has Significant synergistic effect, when the ratio of tebuconazole and allicin is 1:1, 1:2, 1:3, the three combined synergistic factors are greater than 1.5, both have good synergistic effects, of which When the concentration of oxazolol: allicin was 1:3, the synergistic coefficient was 2.64, and the synergistic effect was the most obvious.
The results of field experiment showed that the above formula was soaked for 48 hours, which had a promoting effect on rice seed germination. The control effect on rice seedling disease at heading stage was over 95%, which was significantly better than that of domestic and foreign flavonoids and azoxystrobin. The ester is a seed treatment agent which is a main active ingredient.
