Abstract
The invention discloses a pesticide composition containing halosulfuron-methyl, aminopyralid and nicosulfuron. Active ingredients are halosulfuron-methyl, aminopyralid and nicosulfuron. The pesticide composition has remarkable synergistic effects, has an obviously more excellent effect of preventing and removing annual weeds in cornfields than each single ingredient. Dosage of the active ingredients of the composition is obviously reduced in comparison with dosage of a single ingredient. In addition, weed control spectrum is broadened, weed resistance to herbicides is delayed, and environmental pollution is mitigated.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Synergistic response composition pesticide being active ingredient with halosulfuronmethyl, the acid of chlorine Fampridine, nicosulfuron, be applicable to control of maize field especially with the corn field annual weed that kitchen garden, chenopodium glaucum linn are advantage weeds.
Background technology
Halosulfuronmethyl (halosulfuron-methyl) is absorption agricultural compound in sulfonylurea, can be plant stem-leaf and root absorption, weeds first stop growing then withered, are mainly used in preventing and kill off annual broadleaf weed and sedge weed, have special efficacy to the rhizome of nutgrass flatsedge.
Chlorine Fampridine acid (aminopyralid), for picolinic acid class new herbicides, be mainly used in preventing and kill off annual and perennial broad leaved weed, be widely used in mountain region, grassland, the preventing and kill off of planting site and uncultivated area weeds, the acid of chlorine Fampridine is reacted to potassium hydroxide, sodium hydroxide, ammoniacal liquor etc. and can also be obtained corresponding salt.
Nicosulfuron (nicosulfuron) is absorption agricultural compound in sulfonylurea, can be weeds cauline leaf and root absorption, conduct in plant corpus subsequently, cause sensitive plant growth retardation, cauline leaf chlorisis, withered gradually, generally death in 20-25 days, but when temperature is lower, needed to some perennial weed the longer time.Be mainly used in preventing and kill off corn field annual gramineous weed and part broad leaved weed, also have certain preventive effect to sedge weed, dispenser good drug efficacy before 4 leaf phases after bud, when seedling is large, dispenser drug effect declines.
The present inventor conducts in-depth research halosulfuronmethyl, the acid of chlorine Fampridine, nicosulfuron mixture, find that halosulfuronmethyl, chlorine Fampridine are sour, nicosulfuron mixture has Synergistic to respond to target weeds, especially have obvious Synergistic to respond to kitchen garden (Portulaca oleracea), chenopodium glaucum linn (Chenopodium glaucum).The ternary built of the acid of halosulfuronmethyl, chlorine Fampridine, nicosulfuron is applied to preventing and kill off without relevant report of corn field annual weed.
Summary of the invention
The object of the invention is to solve when prior art Pesticides single dose is used alone the problem that corn field weed easily develops immunity to drugs and actual control efficiency is poor, a kind of efficient, wide spectrum, economy, safety are provided, are conducive to the composition pesticide of the corn field weed comprehensive regulation.
Technical scheme of the present invention is: a kind of composition pesticide, active ingredient is halosulfuronmethyl, the acid of chlorine Fampridine, rimsulfuron, halosulfuronmethyl percentage by weight is in the composition 0.1% ~ 20%, chlorine Fampridine acid percentage by weight is in the composition 0.1% ~ 50%, nicosulfuron percentage by weight is in the composition 0.1% ~ 10%, and all the other are allow in agricultural chemicals to use and acceptable auxiliary element.
Described composition pesticide according to well known to a person skilled in the art method, can be processed into the application forms that the applicable agricultural productions such as suspending agent, oil-suspending agent, water dispersible granules, wetting powder use.
The production technology of the various application forms of described composition pesticide all belongs to existing known technology, does not repeat them here.
Composition pesticide provided by the invention, is applicable to prevent and kill off corn field annual weed.
The frequency of administration of composition pesticide provided by the invention and amount of application change with crops, weeds, weather condition and have small variations, can by the object using suitable dosage reach effectively control.
The present invention expands herbicide spectrum, composition has Synergistic response to target, especially to kitchen garden (Portulaca oleracea), chenopodium glaucum linn (Chenopodium glaucum), there is the response of obvious Synergistic, excellent fix can be provided for preventing and kill off of corn field annual weed, especially kitchen garden (Portulaca oleracea), chenopodium glaucum linn (Chenopodium glaucum) corn field that is advantage weeds, has positive effect for the corn field weed comprehensive regulation.
Embodiment
In order to make object of the present invention, technical scheme and advantage more short and sweet, the following specific embodiment of the present invention is described, but the present invention is only limitted to absolutely not these examples.The following stated is only the good embodiment of the present invention, only for describing the present invention, can not be interpreted as the restriction to scope of the present invention.It should be pointed out that all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
Assays Example 1: the acid of halosulfuronmethyl, chlorine Fampridine, nicosulfuron and the test of the composite Toxicity Determination to kitchen garden (Portulaca oleracea), chenopodium glaucum linn (Chenopodium glaucum) thereof.
Evaluate weed killer herbicide associated form (NY/T 1155.7-2006) according to Colby method, its formula is as follows:
In formula:
A be halosulfuronmethyl alone with certain dosage time fresh weight inhibition to target weeds;
B be the acid of chlorine Fampridine alone with certain dosage time fresh weight inhibition to target weeds;
C be nicosulfuron alone with certain dosage time fresh weight inhibition to target weeds;
N is the weed killer herbicide kind number of mixture;
E
0for the theoretical value to target weeds fresh weight inhibition when halosulfuronmethyl, the acid of chlorine Fampridine, nicosulfuron three kinds of pharmacy mix;
E is halosulfuronmethyl, chlorine Fampridine acid, nicosulfuron three kinds of pharmacy mix time to target weeds fresh weight inhibition be contrast measured value.
Evaluation criterion: work as E
0during ﹣ E > 10%, be expressed as synergistic function; As ﹣ 10%≤E
0during ﹣ E≤10%, show as collaborative summation action; Work as E
0during ﹣ E < ﹣ 10%, show as joint action of antagonism.
The acid of table 1, halosulfuronmethyl, chlorine Fampridine, nicosulfuron and the composite Toxicity Determination result to kitchen garden (Portulacaoleracea) thereof.
