Abstract
The invention discloses a pesticide compound containing fenoxaprop-P-ethyl and quinclorac, and the application thereof; the compound comprises commonly used additive, fenoxaprop-P-ethyl and quinclorac; and the weight part ratio of the fenoxaprop-P-ethyl to the quinclorac is 1:1 to 1:40, and the weight percentage of the total weight of the fenoxaprop-P-ethyl and the quinclorac in the pesticide compound in 5 to 85 percent. The invention is applicable in preventing and removing annual gramineae grassy weeds in a paddy field. The invention has significant synergic effect than the single dose, and the invention reduces the used dose of the pesticide, reduce the medication cost, prolongs the service life of the preparation, and reduces the adverse impact of the pesticide on the ecological environment.
Description
Technical field
The composition pesticide that the present invention relates to is that Yi fenoxaprop and dichloro quinolinic acid are active ingredient, is used to prevent and kill off farmland weed, is particularly useful for preventing and kill off paddy field annual gramineous weed etc.
Background technology
Fenoxaprop (fenoxaprop-P-ethyl) belongs to heterocyclic oxy group phenoxy propionic acid class weed killer herbicide, mainly is by synthetic key enzyme one acetyl-CoA carboxylase of inhibition fatty acid, thereby has suppressed the synthetic of fatty acid.Medicament absorbs the growing point that conducts to meristematic tissue and root by cauline leaf, and effect stopped growing after the dispenser rapidly in 2-3 days, 5-6 days lobus cardiacus chlorosis purpling looks, and meristematic tissue browning look, blade is withered gradually, is the extremely strong cauline leaf inorganic agent of selectivity.In broad leaf crop or broad leaved weed body, can be by very fast metabolism.In soil, be decomposed very soon, succession crop is not had influence.
Dichloro quinolinic acid (quinclorac) is the special efficacy selective herbicide of control barnyard grass in paddy field (Echinochloa crusgalli (L.) Beauv.), and is remarkably productive to 4-7 leaf phase barnyard grass grass.Selectivity is strong, the amplitude broad in dispenser period, and a dispenser can be controlled the barnyard grass grass of whole growth period duration of rice.The seed that this compound can be sprouted, root and leaf portion absorb, and have the characteristics of hormone herbicide, and be similar to the effect symptom of auxin substance.Slight chlorosis phenomenon appears in the barnyard grass grass tender leaf of being injured, and longitudinal stripe and crooked appears in blade.The leaf chlorosis became puce to withered after sandwich barnyard grass was injured; The root of paddy rice can decompose active ingredient, thereby to rice safety.This compound has bigger mobility in soil, can be decomposed by edaphon.Because dichloro quinolinic acid is extensive use of for many years in China, continuously independent all the year round use has made the weeds pesticide resistance constantly strengthen, even continue to increase dispenser dosage, also is difficult to effectively control the generation of farmland weed.
Being mixed of different pesticide species is the common methods of the agriculture resistance disease pest and weed of control.By the formulation of pesticide screening, filter out rational prescription, can effectively improve actual control efficiency, reduce dosage, reduce cost, delay the drug-fast generation of disease pest and weed, be the important means that agricultural synthesis is administered.Fenoxaprop and dichloro quinolinic acid are mixed does not still have report.The prescription screening of inventor Dui fenoxaprop and dichloro quinolinic acid is furtherd investigate, find that fenoxaprop and dichloro quinolinic acid are mixed, in certain mixed ratio scope weeds are shown obvious synergistic effect, after further study, finished the present invention.
Summary of the invention
The objective of the invention is to solve in the prior art develop immunity to drugs problem and actual control efficiency of farmland weed relatively poorly, provide a kind of efficient, low toxicity, quick-acting is good and the lasting period is long, helps the composition pesticide of the farmland weed comprehensive regulation.
Another object of the present invention provides this composition pesticide is used to prevent and kill off farmland weed, is particularly useful for preventing and kill off paddy field annual gramineous weed etc.
Technical scheme:
For achieving the above object, the invention provides the composition pesticide fenoxaprop that a kind of effective ingredient is made up of fenoxaprop and dichloro quinolinic acid and the ratio of weight and number of dichloro quinolinic acid is 1: 1-1: 40 ， fenoxaprops and the percentage by weight of dichloro quinolinic acid weight summation in composition pesticide are 5-85%.
Preferably the ratio of weight and number of ， fenoxaprop and dichloro quinolinic acid is 1: 5-1: 20 ， fenoxaprops and the percentage by weight of dichloro quinolinic acid weight summation in composition pesticide are 15-60%.
Described composition pesticide can be mixed with the application forms that suitable agricultural such as oil-suspending agent, suspending agent, aqueous emulsion, wetting powder, water dispersible granules is used according to well known to a person skilled in the art method.The production technology of various application forms all belongs to existing known technology, does not repeat them here.
Described composition pesticide also contains the required usual auxiliaries of preparation pesticidal preparations, usual auxiliaries is one or more the mixing in solvent, emulsifier, wetting agent, stabilizing agent, dispersant, thickener, defoamer, antifreezing agent, disintegrant, binding agent, filler, filler, the medium etc., be known substance, be various auxiliary agents commonly used in the pesticidal preparations, can change to some extent according to different situations, be not particularly limited.
Described composition pesticide is used to prevent and kill off paddy field annual gramineous weed etc.
Composition pesticide provided by the invention should be noted the leaf phase medication at paddy rice 5-7 when using.
Composition pesticide provided by the invention adopts the method for spraying to use usually, also can adopt agricultural to go up other operation techniques of using as required.
Composition pesticide provided by the invention has following beneficial effect:
1, composition pesticide provided by the invention, show obvious synergistic effect in certain ratio range, the control efficiency of composition is significantly improved than single agent, has reduced the using dosage of agricultural chemicals, reduced drug cost, reduced the adverse effect of agricultural chemicals ecotope.
2, the effective ingredient mechanism of action of composition pesticide provided by the invention has nothing in common with each other, and can overcome the long-term single shortcoming that makes with medicament be easy to generate resistance, prolongs the service life of medicament.
3, composition pesticide provided by the invention helps delaying the drug-fast generation of paddy field annual weed, and the comprehensive regulation of rice weed resistance is had significance.
