Abstract

The present invention discloses an isochloron weedicide. Said invented weedicide is made up by mixing main ingredients (isoprovuron and chlorsulfuron), adjuvants (885, cleaning agent, dispersing agent and Azone) and filling material, and the mixing ratio of the above-mentioned materials is as follows: isoprovuron 1-95%, chlorsulfuron 0.2-8%, 885 1-10%, cleaning agent 1-10%, dispersing agent 1-10%, Azone 1-5% and the rest is filling material. Said invented isochloron weedicide not only can effectively kill field weeds of wild barley, hard grass and lapsana apogonoides, etc., but also can improve safety of rice, raise yield, and its dose is less.

Description

Yilvlong Herbicide

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 belongs to technical field of pesticide.

In agricultural production practice, it has been found that, careless phase change has appearred after sulfonylurea herbicide uses for many years, broadleaf weeds such as monocotyledon weed that Chinese silvergrass, hard grass, caput are careless and so on and lapsana apogonoides present spreading trend, this national agricultural chemicals, plant protection circle have been caused common concern, and urgent hope is developed a kind of to the specific weed killer herbicide of above-mentioned weeds as early as possible.For this reason, the applying date is 950125, and application number is that to disclose a kind of be " " Maitianjing " wetable powder " that main composition is made into chlorsulfuron, chlortoluron for 9511096.6 Chinese invention patent.It is introduced, this weed killer herbicide is to " Chinese silvergrass, hard grass and so on wheatland monocotyledon weed preventive effect is better than the agent of chlorsulfuron list ", but the problem that causes harm that fail thoroughly to solve that control Chinese silvergrass, hard grass, caput are careless, lapsana apogonoides and so on is the weeds of spreading trend, and its residual composition is unfavorable to the ensuing crop growth.

The object of the invention is: at the problem that above-mentioned existing weed killer herbicide exists, it is wide to provide a kind of herbicidal spectrum, and weeds such as, lapsana apogonoides careless to Chinese silvergrass, hard grass, caput have special efficacy, and the Yilvlong Herbicide harmless to ensuing crop.

Yilvlong Herbicide of the present invention is mixed by main composition, auxiliary agent and filler.Wherein main composition is that (chemical structural formula is isoproturon

Chemical name is 3-(4-isoproturon phenyl)-1,1-two-methyl urea) and chlorsulfuron (chemical structural formula is

Phenyl sulphonyl-3-(4-methoxyl group-6-methyl isophthalic acid, 3,5 triazines-2-yl) urea), auxiliary agent is that 885 (formal name used at school is a Ninol alkyl phenol polyoxy ether, and chemical structural formula is

H ₂CH ₂O) ₃H), (chemical structural formula is C to azone ₁₈H ₃₅NO), detergent, dispersant, filler adopts diatomite or potter's clay.Wherein 885 in order to increase lubrication, and the effect of azone is the permeability that strengthens weed killer herbicide, and the effect of detergent is the wetting and suspensibility that improves weed killer herbicide, and dispersant can make various components be able to abundant mixing.

During mixing, feasible proportioning is:

Isoproturon 1-95%

Chlorsulfuron 0.2-8%

885???????1-10％

Detergent 1-10%

Dispersant 1-10%

Azone 1-5%

All the other are filler;

Proportioning is preferably:

Isoproturon 30-0%

Chlorsulfuron 0.5-4%

885???????5-10％

Detergent 5-8%

Dispersant 4-6%

Azone 1-3%

All the other are filler;

Desirable proportioning is:

Isoproturon 68-72%

Chlorsulfuron 0.6-0.8%D

Detergent 4-6%

Dispersant 4%D

All the other are filler.

Experiment shows, the Yilvlong Herbicide that adopts said ratio to make, fast several times of decomposition rates than chlorsulfuron, dosage only is 50% of a chlorsulfuron, can give full play to original drug effect of isoproturon, chlorsulfuron, and it is learnt from other's strong points to offset one's weaknesses, not only effectively kill and remove that Chinese silvergrass, hard grass, caput are careless, lapsana apogonoides etc. is the weeds in field of spreading trend, and dosage reduces, improved to after make the degree of safety of paddy rice, but and the generation of delaying drug resistance, help the volume increase of cereal crops, tally with the national condition.

The invention will be further described below in conjunction with embodiment.

Detergent in the Yilvlong Herbicide of present embodiment is L5

, dispersant adopts NN0, and the proportioning of each component is:

Isoproturon 69.3%

Chlorsulfuron 0.7%

885???????8％

Detergent 5

Dispersant 4%

Azone 1.5%

All the other are filler.

This weed killer herbicide is once more than 200 ten thousand mu of rice field utilizations, and every mu of dispenser about 70 restrains, and the result increases 7.2 ten thousand tons in grain, volume increase 12%, and remarkable in economical benefits is subjected to numerous rural subscribers, especially Jiangsu and Zhejiang Provinces, Anhui, Shanghai one band peasant's welcome deeply.

Below be Jiangsu Institute for Pesticides to Yilvlong Herbicide probation redport that effect of increasing production is done of the present invention, therefrom as can be seen, different green grand effect of increasing production is more even more ideal than isoproturon and chlorsulfuron.
