Abstract
A herbicide for preventing and eliminating both monocotyledonous and dicotyledonous grasses in rice field is prepared from isoproturon and MCPA-sodium or dimethyltetrochlorine as principal components, assistant including "885", CMC and Azone, and filler through mixing, and features broad spectrum, no toxic by-effect and easy preparing.
Description
The present invention relates to a kind of weed killer herbicide, especially a kind of weed killer herbicide that is mixed by major-minor composition the invention still further relates to the manufacture craft of this weed killer herbicide, belongs to technical field of pesticide.
Isoproturon, 2 first, 4 chlorine are main agricultural chemicals that present China is applied to wheatland, paddy field weeding.The former is comparatively effective to killing monocotyledon weeds such as removing barnyard grass in paddy field, and can not effectively kill broad leaved weeds, and paddy rice is had injury; Otherwise the latter, the broad leaved weeds effect of preventing and kill off wheatland is comparatively desirable, and invalid substantially to monocotyledon weed.For can " management of weeds to greatest extent; do not injure the seedlings of cereal crops again ", the applying date is 920604, and application number is that to disclose a kind of be " the ternary mixed herbicide " that main composition is made into nitrofen, hormone herbicide, steriland herbicide for 92106952.9 Chinese invention patent.It is introduced that this weed killer herbicide has advantages such as highly effective and safe, practical phase be wide.But its main composition is complicated, and influence reduces the cost.
The object of the invention is: the deficiency at above-mentioned prior art exists provides a kind of broad weed-killing spectrum, main composition is simple--and different first is swelled weed killer herbicide, thereby satisfies the demand of preventing and kill off of the single, double cotyledon weeds in rice field simultaneously.The present invention also will provide the process for making of this weed killer herbicide in addition.
The grand weed killer herbicide of the different first of the present invention is mixed by main composition, auxiliary agent and filler.Wherein main composition is that (chemical structural formula is isoproturon
(chemical structural formula is 2 first, 4 chlorine sodium
Or 2 first, 4 chlorine (chemical structural formula is
Auxiliary agent is that 885 (formal name used at school is a Ninol alkane phenol polyethenoxy ether, and chemical structural formula is
CMC (formal name used at school is a sodium cellulose glycolate), (chemical structural formula is C to azone
18H
35NO), filler adopts diatomite or potter's clay.Wherein 885 effect is to increase wetting action, and the effect of CMC is to improve suspending power, and the effect of azone is the penetration that strengthens weed killer herbicide.
During mixing, feasible proportioning is:
Isoproturon 5-90%
2 first, 4 chlorine sodium or 2 first, 4 chlorine 5-90%
885?????????????????5-15％
CMC?????????????????0．5-5％
Azone 1-50%
All the other are filler;
Proportioning is preferably:
Isoproturon 10-25%
2 first, 4 chlorine sodium or 2 first, 4 chlorine 8-25%
885?????????????????5-10％
CMC?????????????????0．5-1．5％
Azone 1-3%
All the other are filler;
Desirable proportioning is:
Isoproturon 18-22%
2 first, 4 chlorine sodium or 2 first, 4 chlorine 18-22%
885?????????????????7-9％
CMC?????????????????0．8-1．2％
Azone 1.2-1.8%
All the other are filler.
The manufacture craft of the grand weed killer herbicide of the different first of the present invention is:
1. according to the above ratio various components are stirred in agitator 3-5 quarter, make its even mixing;
2. with airslide disintegrating mill mixed different first is swelled and pulverize, the air pressure of airslide disintegrating mill is controlled at 0.6-0.9Mpa, and the granularity control of pulverizing is at the 300-350 order;
3. check is adjusted, and pH value is controlled at 7-10;
4. the wetting powder weed killer herbicide of making is packed in the packaging bag.
Because the present invention adopts through testing definite proper ratio, the herbicide isoproturon that will be suitable for monocotyledon weed mixes with weed killer herbicide 2 first, the 4 chlorine sodium or 2 first, 4 chlorine that are suitable for broad leaved weed, and added the auxiliary agent that helps to give full play to the weeding property of medicine, suppresses to hinder seedling, so its broad weed-killing spectrum, crop is had no side effect, both can prevent and kill off the monocotyledon weed in the rice field, also can prevent and kill off broadleaf weed wherein, help the volume increase of grain.And its main composition is simple, and preparation is easy, and cost economy is fit to China's national situation.
The invention will be further described below in conjunction with embodiment.
The grand weed killer herbicide of the different first of present embodiment adopts the most economical effective proportioning that draws through repetition test:
Isoproturon 20%
2 first, 4 chlorine sodium or 2 first, 4 chlorine 20%
885?????????????????8％
CMC?????????????????1％
Azone 1.5%
All the other are the potter's clay filler.
Mixing time during making is 1 hour, and the air pressure during comminution by gas stream is 0.7-0.8Mpa, and the granularity after the pulverizing is 325 orders, and pH value is 8-9.
This weed killer herbicide once used in 350,000 mu rice fields, every mu of about 60 grams of dispenser, and the result increases 2.765 ten thousand tons in grain, volume increase 15.8%, remarkable in economical benefits is subjected to expert's favorable comment deeply, and being considered to the utmost point has popularizing value.
The comparative trial account that below to be Institute of Plant Protection, academy of agricultural sciences, Zhejiang Province make present embodiment weed killer herbicide and several existing weed killer herbicide, therefrom as can be seen, the effect of the grand weed killer herbicide of the different first of the present invention is significantly improved than existing weed killer herbicide.
