Description
Technical field
The present invention relates to a kind of composition pesticide and preparation method thereof, especially relate to the double composition pesticide and preparation method thereof of controlling of a kind of nuisanceless entomogenous fungi.
Background technology
The enhancing of Along with people's growth in the living standard and environmental consciousness, the non-polluted farm product market space is increasing.Yet pesticide pollution has become the restraining factors that non-polluted farm product is produced.In recent years, along with the adjustment of crop mix, variation has taken place in working condition and sick worm population structure, and damage by disease and insect generation area strengthens year by year, and the extent of injury is on the rise.Be the generation of control damage by disease and insect, part peasant's violation operation pesticide abuse is for the production of non-polluted farm product has stayed hidden danger; Medication science not in addition, long-term single drug rises the pest pesticide resistance, and drug effect descends, and causes the pollution of agricultural chemicals to air, water source, agricultural product.
CN1386415A discloses a kind of broad-spectrum soluble powdered precursor agricultural chemical for killing pests and bacteria without environment pollution and production method thereof on December 25th, 2002; This agricultural chemicals comprises active matter and various auxiliary agent, and said active matter is the complex compound that formed by the organic iodine activation of cationic surfactant, the complex compound that anion surfactant is formed by the organosilicon activation.It exists raw material components complicated, and production cost is high, and especially, practice shows, owes desirable defective to the control efficiency of fruit tree, vegetables, diseases and pests of agronomic crop; Organic iodine has negative effect to the crops normal growth.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of little to air, water source, pollution of agricultural products, and raw material components is simple, and production cost is low, double composition pesticide and the production method controlled of the nuisanceless entomogenous fungi that control efficiency is good.
The technical scheme that the present invention solves its technical problem employing is: the double composition pesticide of controlling of a kind of nuisanceless entomogenous fungi; Comprise following components in weight percentage: OTAC 4-12% (preferred 5-8%), carboxymethyl cellulose 7-16% (preferred 9-14%), benzene sulfonate 35-48% (preferred 40-45%), sucrose 4-12% (preferred 5-10%), boric acid 5-12% (preferred 7-9%), anhydrous sodium sulfate 12-30% (preferred 16-25%), said each set of dispense is 100% than sum.
Further, the preferred neopelex of said benzene sulfonate.
The double preparation method who controls composition pesticide of the present invention's nuisanceless entomogenous fungi; May further comprise the steps: revolve in the machine at conical double ribbon; Press earlier predetermined weight percent and add OTAC, carboxymethyl cellulose, stirred 10-20 minute, press predetermined weight percent again and add benzene sulfonate, sucrose, boric acid, anhydrous sodium sulfate; Stirred 5-15 minute, and got compound; The gained compound is delivered in the double conic rotary vacuum dryer through first vacuum feeder and pipeline; Under 0.079-0.099MPa, 35-55 ℃ of (preferred 40-50 ℃) condition dry 10-15 minute; Be delivered in the two dimensional motion mixer through second vacuum feeder then; Mixed 10-20 minute.
Method for using: thin up 400-1000 is doubly after (preferred 500-700 doubly), and mode such as can spray is used.
The present invention's nuisanceless entomogenous fungi is double to be controlled in the composition pesticide, and exothermic reaction takes place in hyphal body for active component OTAC and benzene sulfonate, can reach the effect of hitting bacterium for killing insect; In addition; The alkylation group chemical property is active, can not only make the hyphal body internal protein produce deposition, can also work with the phosphate bond of carboxyl, amino, different pyridine radicals or DNA in the hyphal body internal protein; Destroy the cellular metabolism of entomogenous fungi, and then hit bacterium for killing insect; But for having erythrocytic humans and animals, because the oxidation of erythrocyte band oxygen is easy to the active matter oxidation of low concentration is destroyed, making it inactivation, therefore, is safe for humans and animals.
The double composition pesticide of controlling of the present invention's nuisanceless entomogenous fungi; Can be used for the control of insect pests such as fruit tree, vegetables, crops, application comprises coccid, caterpillar, blue or green worm, aphid, acarid, beet webworm, leafhopper, two spotted spider mite, rice leaf roller, rice fulgorid, rice plant skipper etc.; Also can be used for the control by the microbial disease of cause of disease such as fruit tree, vegetables, crops, like banded sclerotial blight, rice blast, solanberry anthracnose, powdery mildew, mandarin tree yellow twig etc.
The double composition pesticide of controlling of the present invention's nuisanceless entomogenous fungi, the pesticide-germicide ability is strong, and control efficiency is good; Utilize that the present invention's nuisanceless entomogenous fungi is double controls composition pesticide pesticide-germicide, noresidue, environmental protection.

The entomogenous fungi of present embodiment is double to be controlled composition pesticide residual test in agriculture university test site, 2007-2008 Changsha and proving ground, academy of agricultural sciences, Zhejiang Hangzhou Zhejiang on citrus and carries out.
In oranges and tangerines campaigns, with 150 times of present embodiment product dilutions, to orange tree (comprising citrus leaf, branch and fruit) and the closed spray pesticide of tangerine garden mould earth 1 time.On the full fruit in Hunan, two places, Zhejiang citrus, clear up the value that the half life period recorded in 2007 and be respectively 3.73 days and 4.08 days, the value that recorded in 2008 was respectively 3.64 days and 3.85 days.The value that the half life period recorded in 2007 of clearing up in the tangerine garden mould earth of Hunan, two places, Zhejiang was respectively 3.92 days and 3.08 days, and the value that recorded in 2008 was respectively 3.99 days and 4.49 days.The result shows that product clears up comparatively fast in the full fruit of citrus and tangerine garden mould earth, Quan Guozhong clears up the half life period and is in 4.08 days, clears up the half life period in the soil all in 4.49 days.Under China's natural environmental condition, OTAC can not cause accumulation residual.
Dispenser dosage: dilute 300 times, to the closed spray pesticide of orange tree (comprising citrus leaf, branch and fruit) (citrus leaf and fruit have soup begin the drippage till); Dilute 150 times, to the closed spray pesticide of orange tree (comprising citrus leaf, branch and fruit) (citrus leaf and fruit have soup begin the drippage till).
Experimental study is carried out in the citrus garden of not executing agricultural chemicals.2 kinds of dispenser dosage, 2 kinds of spraying times (2 times, 3 times, each 7 days at interval) and 6 processing of blank test are established in test.Different time harvesting citrus fruit and tangerine garden mould earth are measured the wherein residual quantity of OTAC respectively after the dispenser, and result of the test is seen table 7, table 8.
The residual result of the test of table 7 OTACs in 2007 in citrus tangerine meat, tangerine peel and citrus garden mould earth
Annotate: 1, LOD is the minimum detectability amount; 2, citrus tangerine meat, tangerine peel are in fresh weight; 3, citrus soil is with dry weight basis.
The residual result of the test of table 8 OTACs in 2008 in citrus tangerine meat, tangerine peel and citrus garden mould earth
Annotate: 1, LOD is the minimum detectability amount; 2, citrus tangerine meat, tangerine peel are in fresh weight; 3, citrus soil is with dry weight basis.
Can know by table 7, table 8; Insect on the control citrus uses the dilution of present embodiment product 300 times citrus to be counted spray pesticide, and dispenser is 2 times at most; Be in tangerine meat that the last dispenser 20d of distance gathers and the tangerine peel and detect OTAC, edible is safe.
