Abstract
The re-compounded pesticide for preventing and killing corn borer is used in preventing and killing Asiatic corn borer mainly. The re-compounded pesticide has chlorpyrifos and permethrine with specific effect on corn borer as the effective components, sand as carrier, diatomite as the coating agent and slow releasing material, and indicator. It is prepared into granule through the technological process including the steps of sieving sand, compounding, coating, colorizing and packing. It has the features of high effect, low toxicity and low residue.
Description
Technical field
The present invention relates to a kind of insecticide that specially kills corn borer, particularly a kind of Compositional type insecticide.
Background technology
Corn borer is the normal generation insect of corn planting belt in the world, and its harm is just having a strong impact on maize yield and quality.Usually adopt breeding for pest resistance, chemical control and biological control, its control efficiency all has much room for improvement.With the chemical control is example, and the medicament of in the past controlling snout moth's larva only has parathion, furans pellet, the thimet of high poison.Because of its high poison, suffer country's forbidding or be about to forbidding, need renewal product efficient, low toxicity in the production badly.
Summary of the invention
The object of the invention provides a kind of Compositional type special-purpose insecticide of control of maize snout moth's larva, is guaranteeing on the basis of insecticidal effect cost to be dropped to minimum, and insecticidal effect is remarkable, is to solve the effective ways that corn borer is caused harm in the Maize Production.
Composition of raw materials provided by the invention and part by weight are as follows:
Chlopyrifos 2.8;
Permethrin 0.2;
Diatomite 4;
Iron oxide red (Fe
2O
3) 0.97;
Specification sand (the 89--92 of Ф=0.7-1.7mm);
Active ingredient is chlopyrifos and permethrin in the above-mentioned prescription, and carrier is a specification sand; The coated slow release material is a diatomite; The caution agent is an iron oxide red.
Processing technology is as follows:
A, screening specification river sand are the standard screen mesh screen choosing of 0.7mm～1.7mm with the aperture.
B, chlopyrifos 2.8, permethrin 0.2 mixes two kinds of former medicines of active ingredient by weight proportion, and it is standby to be crude oil after mixing.
C, be that the specification sand of 89-92 is put into agitator with part by weight, add 58% crude oil then, stirred 10 minutes, and added part by weight again and be 2 diatomite, stirred 10 minutes, add 42% crude oil again, stirred 10 minutes, and added part by weight again and be 2 diatomite, stirred 10 minutes, add part by weight again and be 0.97 iron oxide red, stir packing after 10 minutes.
Advantage of the present invention is: 1, prescription is through meticulously screening comparative analysis, and effect is remarkable: choose at former medicine, except that selecting chlopyrifos for use, also selected insecticidal activity relatively poor relatively permethrin in similar for use.Both proportionings of 14: 1 are best.Its co-toxicity coefficient is up to 182.9, and synergistic effect reaches more than 80%, through update search, at home and abroad there is no the composite product and the patent pertinent literature of these two kinds of medicines.The indoor toxicity measurement result shows that chlopyrifos is LC to the lethal concentration of 50 of corn borer 2 instar larvaes
50=246.527ppm, the lethal concentration of 50 to corn borer 2 instar larvaes of permethrin is LC
50=126.435ppm is LC by the mixture crude oil of optimum formula preparation to the lethal concentration of 50 of corn borer 2 instar larvaes
50=126.801ppm.Analyze above-mentioned laboratory test results, find permethrin to the lethal effect of corn borer 2 instar larvaes significantly better than chlopyrifos, but the former price is also significantly expensive than the latter, and the best proportioning that the present invention screened with less permethrin consumption, has obtained near the drug effect of permethrin to corn borer, co-toxicity coefficient is very high, significantly reduced cost, former medicine per ton reduces cost more than 100,000 yuan, and every mu of control cost reduces more than 10 yuan.2, the present invention is used to prevent and treat the field corn snout moth's larva, executes only to kill by point and removes corn borer, can avoid the field natural enemy is manslaughtered, and has coordinated dispenser preferably and has controlled worm and the contradiction of protecting natural enemy.Different location different year field control effect sees the following form.3, meeting the non-polluted farm product production requirement, is environment-friendly pesticide, can be used for pollution-free food production.
