Abstract
The present invention relates to a cotton defoliant which comprises the following components (weight percent): 52 to 54 wt% of paclobutrazol, 23 to 25 wt% of thidiazuron and 23 to 25 wt% of 885 pesticide synergist. The present invention is wettable powder which has good instant solubility; after the wettable powder is sprayed to cotton plants for 20 days, the defoliation ratio reaches more than 80%, the ripening ratio of cotton bolls is more than 30%, and the medicine effect lasts more than 20 days; the price is low, the cost of each mu is 15 yuan, and the application cost can be reduced by about 50%.
Description
Technical field the present invention relates to the defoliant of a kind of crops, particularly relates to the composition that makes cotton defoliation that used before cotton harvesting.
Background technology is along with the improve of planting cotton mechanization degree, the cotton mechanization of gathering is the inexorable trend of modern agricultural development, before carrying out the mechanical harvest cotton, often sprays defoliant to cotton, reduce cotton leaf as far as possible and mix in cotton fiber, reduce the grade and the value of cotton fiber.At present, the cotton defoliant kind is more both at home and abroad, but still need constantly improve it, reduces the cost of using cotton defoliant.
Summary of the invention the invention provides a kind of cotton defoliant, and it consists of (percetage by weight): paclobutrazol 52～54, grand 23～25, the three kinds of composition optimal proportions of 23～25,885 pesticide synergistic agents of plug benzene are: 16: 7: 7.Wherein the effect of paclobutrazol is to suppress gibberellin to form, the grand effect of plug benzene is the generation that promotes the absciss layer cell, the effect of 885 pesticide synergistic agents is to increase the infiltration capacity of agricultural chemicals at the cotton leaf epidermis, can water-solublely also can be dissolved in oil, have that wetability is good, penetration is strong, reduce pesticide dosage, reduce cost, increase profit, reduce the characteristic of environmental pollution.The present invention is a kind of wetting powder, and instant capacity is good, when its be sprayed onto cotton plant after 20 days the disleave rate reach more than 80%, cotton boll accelerates the ripening rate more than 30%, the drug effect phase continue 20 surplus day, low price, a mu cost is 15 yuan.By test relatively, the present invention is as follows with the treasured that comes off (DROPP) that Germany produces: 20 strain cotton plant disleave rates are 69.5%, and are precious higher by 9.4% than coming off; To the quality influence aspect, than the long 0.2～0.6mm of the precious suede of coming off, regularity comes off precious high by 3.6～1.3%, and the specific strength ratio comes off precious low by 0.3～1.0, and the mic value treasured that comes off differs 0.2～0.8; Every mu can reach the come off defoliation effect of precious 30g of external every mu of usefulness with 45g, can make to use cost and reduce nearly 50%.
Embodiment embodiment one cotton defoliant of the present invention is prepared by following consumption: paclobutrazol 20g; The grand 10.4g of plug benzene; 885 pesticide synergistic agent 10.1g.
Embodiment two cotton defoliants of the present invention are prepared by following consumption: paclobutrazol 24g; The grand 10.5g of plug benzene; 885 pesticide synergistic agent 10.5g.
Embodiment three cotton defoliants of the present invention are prepared by following consumption: paclobutrazol 21g; The grand 10.6g of plug benzene; 885 pesticide synergistic agent 10.2g.
Embodiment four cotton defoliants of the present invention are prepared by following consumption: paclobutrazol 22g; The grand 10.7g of plug benzene; 885 pesticide synergistic agent 10.3g.
Embodiment five cotton defoliants of the present invention are prepared by following consumption: paclobutrazol 23g; The grand 10.8g of plug benzene; 885 pesticide synergistic agent 10.4g.
Embodiment six cotton defoliants of the present invention are prepared by following consumption: paclobutrazol 25g; The grand 10.9g of plug benzene; 885 pesticide synergistic agent 10.6g.
