Description
The present invention is a kind of low toxicity that is used to prevent and treat damage by disease and insect such as fruit tree such as citrus and cotton, tea, mulberry, vegetables, the autofrettage of nuisanceless, efficient novel pesticide-stone sulphur Dormant oils emulsion (trade name: spray is pounced on).
Practice shows: in economic special product crop production such as citrus, for a long time to use the organic chemistry synthetic pesticide, insect easily develops immunity to drugs, injure natural enemy again, drug effect obviously descends as time passes, thereby causes insect rampant again, if improve dosage merely or increase spraying times, will make the aggravation of this rising of farming and adverse side effect, force some agricultural chemicals to accelerate to withdraw from the market, increase many dead wight losses for everyways such as pesticide manufacturing unit, factory and peasant.
As everyone knows, lime sulfur and Dormant oils emulsion (mainly comprising machine oil emulsion, diesel oil emulsion etc.) all are to have century-old above historical traditional agricultural chemicals, they to people and animals' low toxicity, do not have chronic murder by poisoning, environmental pollution is little, substantially do not injure natural enemy, insect is difficult for developing immunity to drugs, and is easy to use, and cost is lower, the former can also promote peel smooth, painted dense, outer skin does not have the effect that improves fruit commodity value concurrently.Therefore, in today that the organic chemistry synthetic pesticide emerges in an endless stream, their usage amounts worldwide still have and increase endlessly, and are lasting.But, must be pointed out that they also have some relatively important disadvantages.
(1) poisoning easily takes place in improper use: lime sulfur spray cloth to the crop after, the part of its effective ingredient calcium polysulfide combines generation sulphur dioxide (SO with airborne oxygen
2).Inferior sulfurous acid (H
2S
2O
3), sulfuric acid (H
2SO
4), become the material that causes poisoning; Dormant oils emulsion spray cloth to the crop after, unsaturated hydro carbons in its Main Ingredients and Appearance machine oil or the diesel oil is met oxygen in the air and is taken place to generate organic acid after the oxidation, also can destroy the semi permeability of plant cell plasmalemma, make cell withered, thereby cause the blade of burning, the generation of acute poisoning such as the pitchy spot appears in fruit, and blade is wilting and even come off.Under the high temperature and drought condition, use above-mentioned any single agent or working concentration too high, poisoning all easily takes place, can not use Dormant oils emulsion at flowering phase of crop especially.
(2) Dormant oils emulsion oil-containing (machine oil or diesel oil) amount is extensive use of and will consumes the bulk petroleum goods all at 90-95%.
The present invention is that emulsification is composite in addition for main composition with the mixing Dormant oils of lime sulfur and machine oil, diesel oil, both inherited and integrated the excellent of each single agent of traditional agricultural chemicals, make composite dose of virulence have synergistic effect than single agent to insect, overcome again poisoning fraud (lime sulfur of alkalescence can in and the Dormant oils emulsion organic acid that uses the back to produce, got rid of Dormant oils emulsion and produced a key factor of poisoning; After Dormant oils and the emulsification of lime sulfur liquid, the effective ingredient calcium polysulfide that has reduced lime sulfur contacts with oxygen in the air and the possibility of oxidation generation poisoning material sulphur dioxide etc.Therefore, after lime sulfur and Dormant oils emulsification are composite, easily cause the factor of poisoning all to obtain overcoming in various degree when two single agent are used separately), simultaneously, gained finished product oil content of the present invention is lacked about half than having Dormant oils emulsion both at home and abroad now, has saved petroleum product widely.
Lime sulfur of the present invention can be the liquid stone sulfur agent (22 °～24 ° Baumes) that boils with conventional method, commercially available dry state lime sulfur (effective ingredient is more than 45%); Dormant oils can be single machine oil or the single light diesel fuel that contains machine oil 0～100%, light diesel fuel 100～0%, or both mixing Dormant oils: emulsifier is to the stable fatty alcohol-polyoxyethylene ether of alkaline solution; Stabilizing agent is polyvinyl alcohol (commercially available dry state product) and fixative, also can use fixative separately, to reduce cost; The emulsification system that above-mentioned substance forms can adopt (or not using) sodium hydroxide or sodium carbonate to regulate pH value.
Example 1: proportioning-lime sulfur (34 °～36 ° Baumes) 38～43%, polyvinyl alcohol (40% aqueous solution) 8～10%, Dormant oils 47～40%, fatty alcohol-polyoxyethylene ether 4～5%, the above weight ratio of fixative 3～2%(, down together).
Implementation process: is the dry state lime sulfur 34 ° of Baumes with water-solubleization of small amount of thermal and thin up to concentration, taking by weighing 90 kilograms of this liquid pours in the 300 liter steam jacket enamel reaction pots, add in advance with 20 kilograms of good 40% polyvinyl alcohol of hot water dissolving, open agitator, stir, add then and mix Dormant oils (machine oil: light diesel fuel=60: 40) 100 kilograms, stir, heat up, drop into 10 kilograms of fatty alcohol-polyoxyethylene ether, 5 kilograms of fixatives continue vigorous stirring in batches, lower the temperature immediately when being warmed up to 91 ℃, continue to be stirred to emulsion and be yellowish-brown, the emulsification material is sent into the colloid mill emulsification of milling, be cooled to normal temperature with pump, get final product can, get 225 kilograms of № 1 finished products.
Example 2: proportioning-lime sulfur (22 °～24 ° Baumes) 42～47.1%, Dormant oils 48.5～42%, fatty alcohol-polyoxyethylene ether 2.5～6%, fixative 6～2.5%, sodium hydroxide 1.0～2.0%.
Implementation process: take by weighing lime sulfur (22 °～24 ° Baumes that boil with conventional method, the clarified solution of elimination dregs) 100 kilogram, pour in the 300 liter steam jacket enamel reaction pots, add again and mix Dormant oils (machine oil: light diesel fuel=60: 40) 100 kilograms, open agitator, heat up, and drop into 10 kilograms of fatty alcohol-polyoxyethylene ether immediately, 10 kilograms of fixatives in batches, 4 kilograms in sodium hydroxide, continue vigorous stirring, when being warmed up to 90 ℃, cooling immediately, and continue to be stirred to emulsion and be yellowish-brown, with pump the emulsification material is sent into the colloid mill emulsification of milling, is cooled to normal temperature and gets final product can, 224 kilograms of № 2 finished products.
Application test is the result show, 100～200 times of aqueous solution of No. 2 finished products of № 1 of the present invention, № are roughly approaching to the control efficiency of citrus red mite, aphid, shell insects, sooty mould, peach scale insect, cotton red spider etc., and its killing rate to insect is higher than or approaching organic chemistry synthetic pesticide commonly used.For example: in a citrus red mite Sheng phase in 4～May, use 100 times of liquid sprays of No. 2 finished products of № cloth tree crown, the killing rate of adult is reached 99～100%, the longevity of residure reached more than 30 days, integrate height when preventive effect is used separately than single agent from killing rate and the longevities of residure two aspect; In May, use 100 times of liquid of No. 2 finished products of №, citrus is vowed that children that point the is situated between killing rate that is situated between reaches 97.22%, and the check plot of using the mixed liquor of 1000 times of liquid of 1200 times of liquid+dichlorvos of 1200 times of liquid+isocarbophoses of 40% flolimat, killing rate only is 91.93%, and the blank district insect density of not spraying medicine then rises 15.86%.
The large tracts of land field is used (comprise citrus, cotton, be like sesame flowers, and the phase is used) result and is shown, phytotoxicity accident does not together take place, and the shortcoming of poisoning easily takes place when having overcome former single agent fully and using separately.
The toxicological test of Zhejiang Province health and epidemic prevention station shows that the acute footpath mouth toxicity of stone sulphur Dormant oils emulsion finished product of the present invention is actual nontoxic, and micronucleus (mutagenesis) result of the test is negative.
