In the autumn, many crops have entered the harvest season, if not taken chemical treatment, the harvest time is very long, will continue until the winter, delaying the planting of the next crop. In order not to delay the sowing of wheat, vegetables and other stubble crops, in production, often use defoliants, in the face of so many defoliants on the market in the end which product has the best effect. Today Xiaobian recommends an excellent defoliant to you, and the crop can be harvested in general 2 to 3 weeks after spraying.
Principle of action
This agent is 540 g/L diospyrrolone suspension agent, which is a compound defoliant formed by the combination of thiphenylron and diospyrrolone. Thiobendon is commonly known as defoliation, defoliating urea is a kind of urea plant growth regulator, used at high concentration, is an excellent cotton leaf removal agent, after spraying, can be quickly absorbed by the leaves of cotton, can promote the synthesis and release of ethylene and abscisic acid in the plant, inhibit the synthesis of auxin and cytokinin, promote the formation of natural separation between the stem and leaves and petioles of cotton, resulting in rapid shedding of cotton leaves. It can also make the leaves still in the green state quickly transfer nutrients to the upper part of the plant tender cotton boll, and the cotton plant will not die, to achieve ripening, leaf removal, yield increase, quality and multi-effect integration. However, thiophenone is susceptible to low temperatures.
Dichoron is a substitute for urea herbicides, which has an assorption conduction effect and a certain touch killing effect. After the agent is absorbed by the plant roots or leaves, by inhibiting the photosynthesis of the leaves, the leaves lose green, the tips and edges of the leaves fade, resulting in the death of the plant due to lack of nutrients. Becomes an extinct herbicide at high doses.
After the mixture of the two, the impact of adverse environmental conditions such as low temperature is reduced, the efficacy of the drug is improved, and the leaf removal is faster and cleaner.
Main features
(1) Promote leaf removal: Thiophenone is used at high concentrations, mainly to make cotton leaves fall off quickly, harvest early, and stubble early. During mechanical harvesting, reduce the contamination of impurities such as leaves.
(2) Increase yield: After the spray of thiobenzophenone, the cotton leaves first lose luster and turn red, and some leaves are slightly necrotic, and the nutrients in the leaves are quickly transferred to the upper tender cotton bells, so that the cotton bells are more fully mature and the yield is increased.
(3) Improve quality: After the spray of thiophenone, the cotton can be prematurely ripened, and the cotton bell spit can be advanced and concentrated, which significantly increases the proportion of cotton before frost. Cotton does not shell, does not fall off, does not fall flowers, increases the length of fibers, improves clothing, and improves the quality and grade of cotton.
Use technology
When the cotton peach has more than 70% cracking, each mu with 540 g / l of thiabenzene dichopyrene suspension agent 10-12 ml, mixed with 30 kg of water, the whole leaves of the cotton plant are evenly sprayed, the cotton begins to fall leaves about 10 days, the spit increases, and the peak of the spit is reached in 15 days.
