Abstract
The invention relates to a herbicide composition containing mesotrione and nicosulfuron, which uses the mesotrione and the nicosulfuron as active ingredients, wherein the weight ratio of the mesotrione to the nicosulfuron is between 1:15 and 15:1. The invention has the advantages of low toxicity, weak allergenicity, few damages to human and livestock, broad herbicide controlling spectrum and remarkable weed control strengthening effect and is suitable for preventing and controlling various weeds in fields of various crops, particularly corn fields.
Description
[technical field]
The invention belongs to the pesticide herbicide field, particularly a kind of herbicidal composition that contains mesotrione and nicosulfuron.
[background technology]
Crops need be used a large amount of weed killer herbicide managements of weeds to retrieve a loss because the harm of weeds causes crop yield to reduce every year for this reason.In recent years, the harm of weeds on various crop such as corn is on the rise, and because weed killer herbicide excessively uses, makes weeds increasing to the resistance of agricultural chemicals, thereby cause weed control efficacy to reduce year by year.The weed killer herbicide kind that therefore, need have better herbicidal effect.
[summary of the invention]
Technical problem to be solved by this invention provides a kind of Herbicidal combinations that contains mesotrione and nicosulfuron as active component, and said composition has wider grass spectrum and the excellent more synergy control efficiency of killing.
The present invention contains the herbicidal composition of mesotrione and nicosulfuron, it is characterized in that by nicosulfuron and mesotrione as active component, the weight ratio of active component is a nicosulfuron: mesotrione=1: 15～15: 1.
The mechanism of action difference of two kinds of active ingredients of herbicidal composition of the present invention is killed grass spectrum difference.Synergy has mutually enlarged herbicidal spectrum between them, and the resistance of weeds reduces, to succession crop safety.
Nicosulfuron (other titles: Yu Nongle; chemical name: 1-(4; 6-dimethyl oxygen yl pyrimidines-2-yl)-3-(3-dimethylamino formylpyridine-2-base sulphonyl) urea or 2-(4; 6-dimethoxypyridin-2-base amino carbonyl amino sulfonyl)-N; the N-dimethyl nicotinamide) (other titles: the Meath is logical with mesotrione; chemical name: 2-(4-mesyl-2-nitro-benzoyl) cyclohexane-1; the 3-diketone) both preferred mass ratioes are 3: 7; the quality percentage composition of active component in Herbicidal combinations is 5～80%, is preferably 10%.
Administration form is according to the applicable pattern of conventional formulation; In all cases, must guarantee that their dispersion is trickle as much as possible and even.
The present composition can be processed into conventional formulation such as A oil suspending agent (OF), B wetting powder (WP), C water dispersible granules (WG), D granula (GR) or E tablet (TA) according to preparation production method conventional on the Pesticide Science.The preferred dosage form of the present invention is oil suspending agent and wetting powder.Therefore the present invention relates to various preparations of above-mentioned herbicidal activity composition and preparation method thereof further.
Now details are as follows with preparation of the present invention and wherein each kind of composition:

2, pilot project and method
(1) safety: after the dispenser, the situation of growing of investigation corn is estimated the safety of reagent agent to corn.
(2) herbicidal effect: every sub-district is got 4 points at random, investigates 1/4 square metre at every, and each investigation in 30 days is once write down weeds kind and strain number respectively after the dispenser, calculates weeds strain preventive effect, and claims it bright careless heavy, calculates bright grass and weighs preventive effect.
(3) result of the test
The I safety: the dispenser " Invest, Then Investigate ", chemicals treatment district corn plant height, Ye Se and blank district basically identical show that reagent agent (1)-phonetic methyl sulcotrione oil suspension concentrate of (3) cigarette is all to corn safety.
The II herbicidal effect
Result of the test sees Table II
By Table II as can be known the phonetic methyl sulcotrione oil suspension concentrate of 16% cigarette of different proportionings to the good preventive effect of annual common weed, to weeds strain preventive effect between 83.6～86.2%, to weeds fresh weight preventive effect between 84.4%～86.6%, effectively the control of maize field weed has guaranteed that the growth of corn is not subjected to weed encroachment.
Above test examples explanation, best proportioning nicosulfuron: methyl sulcotrione oil suspension concentrate=3: 7 pairs common annual gramineae of corn field and broad leaved weed preventive effect are remarkable, weeds strain preventive effect and fresh weight preventive effect are all more than 90%, lasting period is more than one month, basic controlling the crop smothering of corn whole growth phase.And at nicosulfuron: mesotrione=1～15: in 15～1 scopes, annual gramineae and the broad leaved weed common to corn field all have good preventive effect.
