Abstract
The invention discloses a weeding composition containing glyphosate and trichlopyr and an application thereof. The weeding composition comprises the glyphosate, the trichlopyr and the balance of pesticide adjuvant. The weight ratio of the glyphosate to the trichlopyr is 1:20-20:1. The weight sum of the glyphosate and the trichlopyr accounts for 20-80% of the weight of the composition. The weeding composition is used for preventing and weeding weeds in uncultivated areas. The production process is simple, the adopted compound amount is reduced, fewer materials are used, and damage to the environment from the compound is reduced.
Description
Technical field
The present invention relates to Herbicidal combinations and application thereof, active ingredient is glyphosate, trichlopyr, for preventing and kill off uncultivated area weeds.
Background technology
Chemical method weeding is agriculturally one of Main Means controlling weeds, due to the single use of the long-term large area of glyphosate, causes a lot of weeds to develop immunity to drugs.Meanwhile, uncultivated area weeds generation grass is mutually complicated, and not only annual and perennial weed is mixed raw, draft, liana and shrub, and weeds are uneven, seed, low age, the staggered generation of weeds at advanced age, so when weed killer herbicide kind is used alone, all can show defect in a certain respect and limitation.
The whole world find about 30 kinds of serious resistance glyphosate weeds, the Horseweed Herb of China and eleusine indica especially serious to the resistance problem of glyphosate.Occurred serious glyphosate-resistant weeds in areas such as the U.S., Brazil, Argentina, this problem is badly in need of adopting new administrative skill and crop protection products to solve.The universal use exacerbating glyphosate of tolerate glyphosate genetically modified crops, wherein face resistant weed problem at the U.S. nearly 2,800 ten thousand hectares of soybean, corn and cotton crops, 148 kinds can tolerate in the weeds of any type weed killer herbicide altogether, and having defined 14 different species can resistance glyphosate; Plant (about 9,000,000 hectares) area at the Brazil Soybeans of Brazil at least 30% and face resistant weed problem.
Develop glyphosate resistance to delay weeds, glyphosate composition technical development is rapid, as picloram and glyphosate composition, and the patent No.: 201410693132.7; Penoxsuam and glyphosate composition, the patent No.: 201280012616.X; Mesotrione and glyphosate composition, the patent No.: 201210129437.6; Glyphosate and ZPT combination, the patent No.: 201110452668.6; Glyphosate and dicamba combination, the patent No.: 201310266760.2 etc.
Glyphosate (glyphosate), chemical name: N-(phosphoric acid methyl) glycine, glyphosate existence form has glyphosate, glyphosate potassium, ammonium glyphosate, glyphosate-isopropylammonium, glyphosate dimethylamine salt, glyphosate belongs to organic phosphine class inner sucting conduction type steriland herbicide, mainly through suppressing enolpyruvyl shikimene phosphate synthase in plant corpus, thus suppress shikimene to the conversion of phenyl alanine, tyrosine and tryptophan, the synthesis of protein is interfered and causes Plant death.Under ground portion can not only be transmitted to by cauline leaf, and also can conduct between the difference of same plant is tillered, very strong to the underground organization destructive power of perennial dark root weeds.
Trichlopyr (triclopyr), chemical name: 3, 5, 6-trichloro-2-pyridyl fluoroacetic acid, trichlopyr existence form has: trichlopyr, trichlopyr triethylamine salt, triclopyr butoxyethyl ester, trichlopyr is pyridines inner-adsorption conduction-type herbicide, can rapidly by leaf and root absorption, and conduct in plant corpus, act on metabolism of nucleic acid, plant is made to produce excessive nucleic acid, some structural transformations are made to become meristematic tissue, cause blade, stem and root growth deformity, reserve substance exhausts, vascular tissue is by embolism or break, plant is dead gradually.
Screened by formulation of pesticide, filter out rational formula, can effectively improve actual control efficiency, reduce dosage, reduce costs, delaying the drug-fast generation of weeds evil, is the important means of the weeds comprehensive regulation.The present inventor conducts in-depth research glyphosate, trichlopyr combination formula, finds glyphosate, trichlopyr carries out being combined in certain mixed ratio scope has obvious synergistic effect to weeds, after further study, complete the present invention.
Mixture and the application of glyphosate and trichlopyr weed killer herbicide there is no report at present.
Summary of the invention
Technical problem to be solved: the object of the invention is to solve the deficiency in the single use of above-mentioned weed killer herbicide, provides a kind of efficient, wide spectrum, is conducive to the composition of the uncultivated area weeds comprehensive regulation.
Another object of the present invention is applied to by this Herbicidal combinations to prevent and kill off uncultivated area weeds.
Technical scheme: for achieving the above object, the invention provides the Herbicidal combinations that a kind of active ingredient is glyphosate and trichlopyr, the weight ratio of glyphosate and trichlopyr is 1:20 ~ 20:1, glyphosate and trichlopyr weight summation in the composition percentage by weight are 20% ~ 80%, and all the other are insecticides adjuvant.
Glyphosate existence form described in scheme has: glyphosate, glyphosate potassium, ammonium glyphosate, glyphosate-isopropylammonium, glyphosate dimethylamine salt.
Trichlopyr existence form described in scheme has: trichlopyr, trichlopyr triethylamine salt, triclopyr butoxyethyl ester.
According to practical application needs, Herbicidal combinations of the present invention, according to well known to a person skilled in the art method, selects suitable insecticides adjuvant, can be prepared into the one in aqua, wetting powder.
Herbicidal combinations of the present invention is also containing the auxiliary agent of preparation needed for pesticidal preparations, auxiliary agent is the mixing of one or more in solvent, emulsifier, co-emulsifier, wetting agent, stabilizing agent, dispersant, thickener, pH adjusting agent, defoamer, antifreezing agent, filler etc., be known substance, various auxiliary agents conventional in pesticidal preparations, can change to some extent according to different situations, be not particularly limited
The method that Herbicidal combinations of the present invention is watered spraying usually uses, and also can adopt other operation techniques agriculturally applied as required.
Herbicidal combinations provided by the invention has following beneficial effect:
1, glyphosate provided by the invention, trichlopyr combination and application thereof, obvious summation action is shown in certain ratio range, the control efficiency of combination significantly improves than single use, reduce using dosage, decrease times for spraying, reduce drug cost, decrease the adverse effect of agricultural chemicals to ecotope.
2, glyphosate provided by the invention, trichlopyr composition and application thereof, the combination of two kinds of effective ingredients, not only can make up the deficiency of glyphosate single dose to resistant weed weak effects such as Horseweed Herb, field bindweed, eleusine indicas, and can make up trichlopyr can only prevent and kill off broad leaved weed and the defect substantially invalid to other weeds classes.
3, glyphosate provided by the invention, trichlopyr composition and application thereof, glyphosate, trichlopyr mechanism of action are different, the shortcoming that long-term single use easily produces resistance can be overcome, extend the service life of compound, to the comprehensive regulation important in inhibiting of Weed Resistance.
4, glyphosate provided by the invention, trichlopyr composition and application thereof, production technology is simple, reduces compound amount, reduces material and uses, alleviate compound to environmental injury.
