Downy mildew is a common disease on rapeseed, which occurs during the whole growth period of rapeseed, causing the leaves to die, the inflorescences are fat and deformed, and they are not strong or strong. The disease is caused by downy mildew infection, and the rapeseed is prone to develop in the weather of low temperature and rain or cold and cold. In order to screen out effective control agents, we selected 6 kinds of agents for field trials.
This product is used in collecting high-quality DNA/RNA samples from saliva and can be used in various biological experiments such as enzymatic hydrolysis, PCR, and next-generation sequencing. It is widely used for the collection and preservation of specimens in hospitals, scientific research institutions, and families. The collection process is easy and painless, and will not cause any damage or discomfort to the human body.

The test agents were 72% nail cream, manganese zinc wettable powder, 30% dimethomorph wettable powder , 80% dimethomorph wettable powder, 77% copper hydroxide wettable powder, 25%. A cream · downy mildew WP and 75% chlorothalonil wettable powder. In the flowering stage of rapeseed, the corresponding concentration spray was diluted, and the disease index of each treatment was investigated before and 7 days, 14 days and 21 days after the drug, and the corresponding corrective effect was calculated.
The test data showed that the above six drugs have certain control effects against rape downy mildew. 7 days after the drug, the 80% dimethomorph wettable powder 2500 times solution has the highest corrected control effect, which is 51.93%, which is significantly higher than 30% dimethomorph WP 800 times solution and 25% nail cream and cream. The control effect of the mildew wettable powder 500 times liquid treatment is extremely higher than that of the treatment of 72% of the nail cream and manganese zinc wettable powder 600 times liquid; the treatment of 72% nail cream and manganese zinc wettable powder 600 times liquid The correct correction effect is the lowest, which is 32.21%. 14 days after the drug, 72% of the nail cream·manganese-zinc WP 600 times solution has the highest correction effect, which is 32.21%, which is significantly higher than the 77% copper hydroxide wettable powder 800 times solution. The difference was not significant with other treatments; the 80% dimethomorph wettable powder 2500 times solution was the next, which was 46.28%. 21 days after the drug, 72% of the nail cream·manganese-zinc wettable powder 600 times solution has the highest corrected control effect, which is 62.17%, which is significantly higher than the 77% copper hydroxide wettable powder 800 times solution, but with The difference of other treatments was not significant; 80% dimethomorph wettable powder 2500 times solution was the next, which was 46.28%.
The test results show that 72% of the nail cream·manganese-zinc wettable powder has high control effect and long duration, but the quick-acting effect is poor. When rapeseed downy mildew occurs rapidly, it may not be conducive to controlling the disease in a short time. It can kill 77% of copper hydroxide WP. The correct control effect is the lowest at 14 days and 21 days after drug, indicating that its effect on controlling downy mildew is not good. The 80% dimethomorph wettable powder achieved 51.93% control effect 7 days after administration, which was the quickest in the 6 kinds of agents, and maintained 52.72% of the control effect 21 days after the drug, indicating that it The effect of the drug lasts longer. At 7 days, 14 days and 21 days after the drug, the corrective effects of the control agent 75% chlorothalonil WP were 39.21%, 41.11% and 49.46%, respectively, and the control effect was general. According to the comprehensive analysis, 80% dimethomorph wettable powder has good quick-acting effect on the control of rapeseed downy mildew, and it has a long duration and can be widely applied in production.
