Abstract
The invention discloses a ternary mixed weeding composition for a paddy field. Cyhalofop-butyl, penoxsulam and bentazone are used as active ingredients. The ternary mixed weeding composition comprises 1-20wt% of cyhalofop-butyl, 1-10wt% of penoxsulam, 1-30wt% of bentazone and the balance an herbicide assistant. According to application demands, the ternary mixed weeding composition can be processed to form a suspending agent, wettable powder or water dispersible granules. The ternary mixed weeding composition is suitable for preventing and removing annual weeds in the paddy field. The ternary mixed weeding composition has weeding effects obviously superior to those of single-ingredient herbicides, has a wide weeding spectrum, improves actual effects, delays production of herbicide resistance of weeds, and saves time and labor.
Description
Technical field
The present invention relates to a kind of Herbicidal combinations of preventing and kill off paddy field annual weed, is to take cyhalofop-butyl, penoxsuam and bentazone as active ingredient.
Background technology
Chemical method weeding is one of Main Means of paddy field prevention and control weeds.Paddy field weed generation grass is complicated mutually, and the multiclass weeds such as grassy weed, broad leaved weed, sedge family are mixed raw, and single variety weed killer herbicide is used can not solve paddy field weed, all can show defect and limitation in a certain respect.By variety classes weed killer herbicide science, be mixed, there is the herbicidal spectrum of raising, promote actual effect, time and labour saving advantage.
Only kind paddy rice to tight security in cyhalofop-butyl virtue phenoxy phenoxy propionic acid weed killer herbicide is interior suction conductivity weed killer herbicide.Blade and leaf sheath by plant corpus absorb, and phloem conduction, accumulates the meristem zone in plant corpus, resist acetyl-CoA carboxylase, fatty acid is synthesized and stop, the growth division of cell can not normally be carried out, film systems etc., containing fat structural deterioration, finally cause plant dead.From cyhalofop-butyl, be absorbed into weeds Mortality Ratio slower, generally need 1-3 week.
Penoxsuam belongs to sulfonylurea, translocated herbicide, through cauline leaf, young shoot and Root Absorption, by xylem and phloem, conducts to meristematic tissue, suppresses plant strain growth, makes growing point chlorosis, and after processing, 7-14d terminal bud reddens, necrosis, and 2-4 week plant is dead; Penoxsuam is strong inhibitor of acetolactate synthetase, and medicament presents slower, needs certain hour weeds just dead gradually.Penoxsuam can effectively be prevented and kill off barnyard grass, moleplant seed and annual sedge weed, and effective to numerous broad leaved weeds.
Bentazone is optionally herbicide after seedling of contact killing type tool, for cauline leaf processing in seedling stage, by blade, is contacted and is worked.Dry land is used, and first by blade face, is permeated and is transmitted to inhibited photosynthesis in chloroplast.Paddy field is used and can be permeated and can pass through root absorption by blade face, is transmitted to cauline leaf, strongly hinders weeds photosynthesis and water metabolism, causes nutrition hungry, and physiological function is lacked of proper care and lethal.Active ingredient is detoxified to active weak glycoconjugates metabolism in tolerable crop body, and to crop safety, after dispenser, 6-18 week bentazone can be decomposed by microorganism in soil.
Variety classes weed killer herbicide is mixed, have herbicidal spectrum wide, promote actual effect, delay herbicide resistance, time and labour saving advantage.By mixed pesticide, screening, can effectively improve actual control efficiency, reduce dosage, reduce costs, delay the generation of herbicide resistance, is the important means that agricultural synthesis is administered.The inventor conducts in-depth research the formula of cyhalofop-butyl, penoxsuam and bentazone, find that cyhalofop-butyl, penoxsuam and bentazone are mixed, in certain mixed ratio scope, paddy field annual weed is had to synergy or summation action, after further study, completed the present invention.
Summary of the invention
The object of the invention is to solve in prior art to farmland weed develop immunity to drugs problem and actual control efficiency poor, provide a kind of efficient, low toxicity, quick-acting is good and the lasting period is long, is conducive to the composition pesticide of the farmland weed comprehensive regulation.
Another object of the present invention is to provide this Herbicidal combinations for preventing and kill off paddy field annual weed.
Technical scheme: for achieving the above object, the invention provides a kind of Herbicidal combinations of preventing and kill off paddy field annual weed, to take cyhalofop-butyl, penoxsuam and bentazone as active ingredient, the percentage by weight of cyhalofop-butyl in composition is 1%～20%, the percentage by weight of penoxsuam in composition is 1%～10%, the percentage by weight of bentazone in composition is 1%～30%, and all the other are insecticides adjuvant.
Herbicidal combinations of the present invention is suspending agent, wetting powder or water dispersible granules in the formulation of practical application.
The insecticides adjuvant using in Herbicidal combinations of the present invention comprises solvent, emulsifier, wetting agent, stabilizing agent, dispersant, thickener, PH conditioning agent, defoamer, antifreezing agent, deionized water, filler etc., be all various auxiliary agents conventional in Pesticide formulation, concrete composition and consumption require to determine by simple test according to formula.
The production technology of the various application forms of composition pesticide provided by the invention all belongs to existing known technology, does not repeat them here.
Composition pesticide provided by the invention, conventionally adopts and is watered spray method use, also can adopt as required other operation techniques of the upper application of agricultural.
Composition pesticide provided by the invention, should be in the 2 leaf phases of paddy rice to the shooting stage in when application, and annual weed was used before the phase to 5 leaves after being unearthed.
Composition pesticide provided by the invention has following beneficial effect:
1. a kind of paddy field weed composition of preventing and kill off provided by the invention, in certain ratio range, its synergy shows obvious synergistic effect, and the herbicidal effect of composition is significantly improved than each single dose, expansion herbicidal spectrum.
2. a kind of paddy field weed composition of preventing and kill off provided by the invention, they are different containing active ingredient mechanism of action, and the application of composition can delay or overcome the generation of herbicide resistance, is conducive to the weeds comprehensive regulation.
Embodiment
The present invention describes by following specific embodiment, but the invention is not restricted to following specific embodiment.In these embodiments, unless otherwise indicated, all percentage is all weight percentage.
