Abstract
The present invention relates to a weeding composite for corn field and its preparation method. Said composite contains (by weight portion) 1-3 portions of nicosulfuron, 30-50 portions of 2,4-D butyl ester, 0.1-3.0 portions of camphor, 0.3-5.0 portions of azone laurocapram, 0.1-3.0 portions of furpentine, 0.05-2.0 portions of ethyl ether, 6-12 portions of emulsifier 8206, and dimethyl benzene for replenishing to 100 portions. Its preparation method includes the following steps: stirring and mixing nicosulfuron, 2,4-D butyl ester, emulsifier 8206, dimethyl benzene and camphor in the reaction still for 1-4 hr., then placing azone laurocapram, furpentine and ethyl ether into reaction still, stirring and mixing them for 40-80 min.
Description
One, technical field
The present invention relates to a kind of Herbicidal combinations and method for making thereof, more specifically say so a kind of oil emu Herbicidal combinations and method for making thereof.
Two, background technology
At present, it mainly is ureas that the corn stem leaf of domestic use is handled weed killer herbicide, and single herbicide applications has caused the change of field grass phase, and herbicidal effect reduces.And it is slow that carbamide herbicides is knocked down speed, and just the effect phase reaches 14 days, lacks capacity of competition on market.
Nicosulfuron can be used for corn field and prevents and kill off annual or perennial grassy weed and some broad leaved weed.Use behind the bud, the corn 3-4 leaf phase, weeds emerge and reach 5cm left and right sides plant height, and with 4% nicosulfuron (corn is happy) suspending agent 50-75ml/ mu (summer corn), 66.67-100ml/ mu (northern spring corn) adds 30 kilograms of cauline leaf sprayings of water to be handled.But, this weed killer herbicide price height, the grass spectrum is narrow extremely, and the dispenser phase disadvantage of weak point is also fairly obvious.
2, the 4-D butyl ester is the hormone-type selective herbicide, has stronger interior suction conductivity.Cauline leaf was handled after it also was mainly used in seedling, and its plate-out ability is good, and penetration is strong, entered easily in the plant corpus, was difficult for by rain drop erosion.Its shortcoming is to have very strong volatility, the soup droplet can be in air drift far, sensitive plant is injured, its drug effect of environmental influence and safety, it is mainly used in gramineous crop and prevents and kill off broad leaved weed.
Three, summary of the invention
Purpose of the present invention just is to work out a kind of corn stem leaf and handles Herbicidal combinations, knocks down speed to improve it, enlarges to kill the grass spectrum, thereby improves herbicidal effect, reduces the pesticide resistance of weeds.
Another object of the present invention is the preparation method who works out above-mentioned Herbicidal combinations.
Researcher of the present invention carries out rational compatibility with ureas and phenoxy carboxylic acid, has added medicaments such as synergist again, improving its plate-out ability, permeability and herbicidal effect, and has formed a kind of new Herbicidal combinations of the present invention.
A kind of corn field stalk leaf weedicide composite of the present invention, it contains:
Nicosulfuron (2-(4, a 6-dimethyl pyrimidine-2-carbamyl aminosulfonyl) N, N-dimethyl nicotinamide, C
15H
18N
6O
6S, nicosulfuron) 1-3 weight portion.
2,4-Dbutylate 2,4-D butyl ester, (2,4 dichloro benzene oxygen base n-butyl, C
12H
14Cl
2O
3, 2,4-Dbutylate) the 30-50 weight portion.
Camphor 0.1-3.0 weight portion;
Azone 0.3-5.0 weight portion;
Turpentine oil 0.1-3.0 weight portion;
Ether 0.05-2.0 weight portion;
Emulsifier 8206 6-12 weight portions;
Mend to 100 weight portions the Herbicidal combinations of formation with dimethylbenzene.
Add camphor in the Herbicidal combinations of the present invention, played the effect of affine, wetting and spread.Azone has played osmosis, and turpentine oil has played adhesive attraction.Emulsifier 8206 is a kind of mixtures, thereby does not have chemical name, and the used emulsifier 8206 of the present invention is that Binzhou Chemical Plant, Shandong Prov. produces.Said weight portion can be gram, two, jin, kilogram, ton etc.
The method for making of a kind of corn field stalk leaf weedicide composite of the present invention, at first get the raw materials ready by following proportioning, nicosulfuron 1-3 weight portion, 2,4-D butyl ester 30-50 weight portion, camphor 0.1-3.0 weight portion, azone 0.3-5.0 weight portion, turpentine oil 0.1-3.0 weight portion, ether 0.05-2.0 weight portion, emulsifier 8206 6-12 weight portions, mend to 100 weight portions with dimethylbenzene, with the raw material nicosulfuron, 2, the 4-D butyl ester, emulsifier 8208, dimethylbenzene, camphor drops in the reactor and at room temperature mixed in reactor 1-4 hour, drop into azone, turpentine oil, ether is in reactor, in reactor, mixed under the room temperature 40-80 minute, and formed Herbicidal combinations of the present invention.
Said room temperature is 15-30 ℃, with nicosulfuron 2,4-D butyl ester, emulsifier 8206, dimethylbenzene, camphor place reactor to mix 14 hours in 15-30 ℃, again to mix 2-3 hour for well, adding azone, turpentine oil, ether at 15-30 ℃, mixed 40-80 minute in reactor, were advisable to mix 50-70 minute again, its mixing speed does not have any influence to the quality of product, and Herbicidal combinations of the present invention is an emulsifiable concentrate.
The preventive effect method of Herbicidal combinations of the present invention, field trial is divided the sub-district comparative trial, the Da Qu comparative trial of demonstrating, small plot experiment is handled for every kind and is repeated 4 times, Herbicidal combinations of the present invention (cigarette. drip) be a kind of emulsifiable concentrate, the concentration that needs according to use during use is diluted to required concentration with clear water.Test dosage of the present invention is a 40-100 gram/mu, generally dilutes 300 times-750 times.Mix the back in the corn 3-4 leaf phase, the weeds 2-5 leaf phase sparges on the corn field weed.
The advantage of corn field stalk leaf weedicide composite of the present invention and method for making thereof just is:
1 corn field stalk leaf weedicide composite of the present invention, behind two kinds of herbicide mixtures, learn from other's strong points to offset one's weaknesses mutually, produced synergy, enlarged and killed the grass spectrum, improved preventive effect, remedied single with medicament to main assorted defective of drawing the preventive effect difference, a drug can effectively be prevented and kill off annual monocotyledon weed and broadleaf weed in all one's life; Added synergist, improved herbicidal effect again, its herbicidal effect sees Table 1, table 2, table 3.The data of table 1, table 2, table 3 are picked up from the test data of academy of agricultural sciences, Shandong Institute of Plant Protection's test report and department of agriculture of College of Crops, China Agricultural Univ. weeds chamber.
