In the process of cotton cultivation by cotton farmers, there are many problems with the use of cotton. In response to the two questions raised by cotton farmers, the analysis of China's pesticide network Xiaobian:
1) Does it need to be disinfected for the coated cotton seedling bed soil?
Most of the seeds currently used for cotton planting in China are cotton seeds that have been treated with a coating agent after defoaming with foam acid, which is usually called a coated cotton seed. The agent in the coating agent can be eliminated. The pathogens adhering to cottonseed can make various soil-borne bacteria that are lurking in the soil still need to use fungicides to eliminate or control. If we don't pay attention to this link, it will be the best cotton seedlings. Infected with stem blight, blight and anthracnose, etc. Therefore, when raising the seedling bed in the whole cotton camp, it is necessary to use the chemicals in the soil of the seedbed to prevent and cure diseases. Many, for example, 25 percent of the fungicide carbendazim 1200-1500 times solution, 2.5 percent of the Kollesha seed coating agent 500 times solution, and 25 percent of the propiconazole cream 5 About 8 grams of water and 60% of the hundred taels of water-dispersible granules are added to them about 30 kg of water. The soil of the seedbed should be sprayed before the sputum is made. penetration. After the cotton seedlings are out, it is necessary to take the opportunity to spray to avoid the invasion of foreign pathogens. We can spray the medicinal agent such as 1:2:200 Bordeaux mixture or the protection of 0.1%.
2) Can you use herbicides on cotton seedling beds?
In cotton seedlings, there is usually a problem of grass damage. In some cases, weeds may also cause grass seedlings, which seriously affect the normal growth and development of cotton seedlings. The serious grass shortage caused by the seedbed is usually caused by two factors. The first is that for the newly selected seedbed, there is no timely ploughing and tilling. The weeds are not covered by winter stalks, spring sun, and clean. The residual weeds are propagated; the second is the possibility of applying farmer's fertilizer that is not thoroughly decomposed, bringing the weed seeds into the seedbed and then rapidly multiplying. Therefore, it is necessary to apply the herbicide before the seedlings are grown after cotton planting. We can choose to use 48% of the cable emulsifiable concentrate, 150 ml to 200 ml per mu, or 72% of the dur emulsifiable concentrate. On average, 150 ml per mu, add 60 kg to 80 kg of water for spraying. We can also choose to use 23% of bed grass net emulsifiable concentrate. The average use of 100 ml to 120 ml per acre adds 80 kg of water. Spraying, this can effectively avoid weed damage.
