Description

A kind of manufacturing technology of agricultural chemicals with enhanced efficacy

The present invention relates to pesticide field, is a kind of composition and production method thereof of agricultural chemicals specifically, international Patent classificating number A01N.

Existing technology proves, Olivomitecidin (Abamectin) is the insecticide that a kind of and organic phosphor, carbamate and pyrethroid insecticides have diverse mechanism of action, has the insect of resistance to have excellent control efficiency for above medicament., rise as a kind of rotating medication with it, have very big meaning the service life of prolongation agricultural chemicals for delaying pest resistance to insecticide.With the dosage form supply the market of missible oil, the content of its preparation is between 1-5% usually for Olivomitecidin.But owing to they cost an arm and a leg, the use cost height, and can not on field crop, extensively and economically use.For this reason, reduce its use cost, it can be had great importance on grain, cotton, vegetables, fruit tree in the application of economy ground.

Therefore, manufacturer's suggestion adds effect and the reduction use cost of light oil to improve Olivomitecidin in use, but the amount that adds light oil substantially exceeds the consumption of agricultural chemicals itself, thereby can only take the field now to mix used mode, and is very inconvenient for the user.Moreover,, also be very limited for the raising of drug effect, usually about 10-20% even added light oil.

Existing technology proves, sulphur AKH7088 (Fomesafen) chemical name: 5-[2-chloro-4 (trifluoromethyl) phenoxy group-2-nitrobenzene acid amides is a kind of weed killer herbicide that soybean field broad leaved weed is had good preventive effect effect, but cost an arm and a leg, use cost is higher, and under the usage amount of recommending, because the longevity of residure is longer, after some batches crops there is poisoning.For improving effect, manufacturer's suggestion can add the non-ionic surface active agent Agral90 of spray amount 0.1% in use, the general effect that improves is about 10-20%, the unit are usage amount can not reduce significantly, still can not solve the drug injury problem of residue to the back stubble, also electricity reduces use cost significantly, more because the consumption of auxiliary agent is also bigger, must carry out now mixing existing usefulness, bring inconvenience to use.

Existing technology proves, pyrrole chlorine diclofop-methyl (Fluazifop-p-butyl) chemical name: (R)-2-[4-(5-trichloromethyl-2-pyridine oxygen base) phenoxy group] butyl propionate is for preventing and kill off the weed killer herbicide of grassy weed efficiently, has good preventive effect for grassy weed.Has market widely in China.But because this medicine price is higher, domestic in addition still do not have this medicine production, so need a large amount of foreign exchange imports of cost every year, to satisfy domestic market demand.For improving effect, manufacturer's suggestion can add certain amount of surfactant in use, can improve about effect 10-20%, and this can not make the cost of medication reduce significantly, and the large usage quantity of general auxiliary agent, needs the existing existing usefulness of mixing, and uses inconvenient.

The objective of the invention is to utilize respectively above three kinds of agricultural chemicals as effective ingredient, be mixed with new composition, these compositions can significantly improve the control efficiency of above each medicament to original separately controlling object.

Content of the present invention below is described in detail in detail.

The wide volt of one of composition of the present invention fourth is made up of the cream preparation and the builder GAE (trade name is extensively imitated liquid, is produced by the permanent logical fine chemistry industry Applied Research Laboratory in Chengdu, Sichuan Province) that with Olivomitecidin (Abamectin) are effective ingredient.

The present invention extensively lies prostrate the detailed prescription following (percentage by weight) of fourth:

Content is 1-5% Olivomitecidin cream preparation 80-92%

GAE 8-20％

Fig. 1 is technological process of the present invention.

Special addition agent GAE can improve the control efficiency of Olivomitecidin to insect, when the addition of GAE is 8% when above of commercially available Olivomitecidin amount of formulation, though it is the consumption of Olivomitecidin preparation has reduced half, still suitable with positive usual amounts to the control efficiency of diamond-back moth.Thereby reduced the usage amount of agricultural chemicals, reduced environmental pollution, because the price of 10% GAE far below the price of second half content at the Olivomitecidin missible oil of 1-5%, therefore, after using GAE, has reduced the use cost of unit are significantly.

Below be result of the test: Guangdong 1994

Controlling object: 1 day effect insect population rate % that goes down behind the diamond-back moth medicine

Olivomitecidin missible oil 50ml/ mu 72.12

Wide volt fourth 27.5ml/ mu 74.43

Clear water blank 7.04

Below be described in detail the embodiment of the invention, but the invention is not restricted to this example.

Get 10 kilograms of cream preparations that contain Olivomitecidin 1-5%, add the GAE1 kilogram, fully stir evenly mixedly, promptly become wide volt fourth missible oil.

Two beans prestige of composition of the present invention are by being that effective ingredient and builder GAE (the GAE trade name is extensively imitated liquid, is produced by the permanent logical fine chemistry industry Applied Research Laboratory in Chengdu, Sichuan Province) and corresponding surfactant are formed with sulphur AKH7088 (Fomesafen) sodium salt or sylvite.

Detailed prescription of the present invention is as follows:

Sulphur AKH7088 sodium or sylvite 10-30%

GAE 5-30％

Surfactant 5-30%

Water 40-80%

Surfactant in this composite formula can be water-soluble non-ionic surface active agent or anion surfactant and their composition.

Fig. 2 is the process chart of this composition

Special addition agent GAE can improve the preventive effect of sulphur AKH7088 to weeds, and is when the content of GAE is 5% when above of amount of formulation, though the usage amount of unit are sulphur AKH7088 has reduced half, suitable with positive usual amounts to the preventive effect of weeds.Thereby reduced the usage amount of agricultural chemicals, reduced environmental pollution, advantageously, because the sulphur AKH7088 can produce poisoning to succession crop under positive usual amounts, the reduction owing to consumption behind the adding GAE may address this problem.Because the price of 10% GAE is far below second half price of sulphur AKH7088, therefore, adds with GAE the use cost of agricultural chemicals is reduced significantly.
