Abstract

The present invention relates to a compound preparation using sesame oil as synergist and using pyrethroid and organo phosphorous chemicals as main effective components, which is applicable to fruit tree, vegetables, crops and cotton etc. for curing and preventing insect pest, and is specially suitable to such district where resistance to the action of said two drugs has been taken place. Said preparation is very cheap and is only 25-40% of the cost of dimethylcyclopropanecarboxylate, but it features high efficient, wide spectrum, long active period and the drug-fast will not become even continuously applyig over the years.

Description

Composite preparation of quasi-pyrethrin and organic phosphorus pesticide

The present invention relates to a kind of agricultural drugs preparation formulation, be applicable to the insect pest of farm-forestry crops such as control fruit tree, vegetables.

Pyrethroid pesticide is efficient, low toxicity, dosage is few, the longevity of residure is long, and organophosphorous pesticide also is the agent of high-efficiency broad spectrum insects, but this two classes agricultural chemicals is in recent years owing to use continuously, and insect strengthens its pesticide resistance, makes the drug effect decline of its application.No. 105081 invention disclosed patent applications of CN are with fenpropathrin and the composite use of organophosphorous pesticide, and drug effect it is said to be increased to some extent, but not obvious to the drug-fast inhibition of insect pest, but cost is still higher.

Purpose of the present invention, it is stronger to provide a kind of drug effect, and the pesticide resistance of lower dawn of cost to insect pest has very strong inhibiting agricultural chemicals to duplicate preparaton.

Technical solution of the present invention is as follows: the complex preparation of a kind of pyrethroid and organophosphorous pesticide for mainly containing effective constituent, also is synergist with pyrethroid and organophosphorous pesticide with sesame oil.

This complex preparation, the ratio of its sesame oil, chrysanthemum ester and organic phosphor effective ingredient is 1: 1-3: 2-100.

Pyrethroid can adopt decis (decis), kills chrysanthemum ester (Belmark) and cyhalothrin etc.; Organophosphorous pesticide can adopt acephatemet, phoxim etc.Composite good preparation, thin up 2500-5000 doubly sprays.

This complex preparation directly adopts the missible oil of commercially available agricultural chemicals to process composite; Concentration is significantly less than aforementioned application for a patent for invention, therefore cost is also cheaper, but since with sesame oil as synergist, sesamin in the sesame oil (sesame oil), sesamol and sesamolin etc. have very strong synergistic effect to pyrethrins insecticide, so still can play good kill pests, pest control effect even concentration is very low when this complex preparation uses.This preparation can be widely used in the pest control of crops such as fruit tree, grain, vegetables, cotton, and aphid, scale insect, all kinds of heart-eating worm, cabbage caterpillar, tortrix moth, two spotted spider mite etc. are all had strong killing power, and the lasting period is 15-22 days.Use this preparation cost than the low 60-75% of pyrethrin pesticide,, the more important thing is the insect pest pesticide resistance is suppressed obvious especially, can use continuously for many years and do not develop immunity to drugs than the low 40-50% of acephatemet, phoxim pesticide.

Its control efficiency sees following table for details:

1, effect contrasts such as control peach fruit borer, dichocrocis punctiferalis

Medicament uses multiple behaviour in service fruit rate (%) well

2.5% bromine oxygen chrysanthemum ester 4000 long-term 90

50% acephatemet (phoxim) 1000 " 80

Preparation 3000 " 98 of the present invention

2, anti-ly eliminate aphis, the contrast of two spotted spider mite effect

Medicament uses multiple behaviour in service fruit rate (%) well

2.5% decis 4000 long-term 80

50% phoxim (acephatemet) 1000 " 70

Preparation 4000 " 95 of the present invention

Effects such as control cotton bollworm, cabbage caterpillar also all are better than aforementioned two class agricultural chemicals.The inventor is planting orchard advance copy invention preparation in recent years certainly, and cost reduces greatly, but save time, the saving of labor, the present invention if can implement to promote, its economic benefit and social benefit will be very considerable.

Embodiment 1: 40 milliliters of decis 2.5% missible oil, and 40 milliliters of 50% phoxim emulsifiable concentrates, 1 milliliter in sesame oil, thin up is 2500 times during use.

Embodiment 2: kill 15 milliliters of chrysanthemum ester 20% missible oil, 600 milliliters of 50% acephatemet missible oil, 1 milliliter in sesame oil, 5000 times of uses of thin up.

Embodiment 3: 50 milliliters of cyhalothrin 2.5% missible oil, 100 milliliters of 50% phoxim emulsifiable concentrates, 1 milliliter in sesame oil, 3000 times of uses of thin up.

Embodiment 4: 100 milliliters of decis 2.5% missible oil, 1 milliliter in 300 milliliters of 50% acephatemet missible oil and sesame oil, 4000 times of uses of thin up.

Embodiment 5: kill 10 milliliters of chrysanthemum ester 20% missible oil, 50% phoxim emulsifiable concentrate adds 1 milliliter in sesame oil for 200 milliliters, 3500 times of uses of thin up.

Embodiment 6: 120 milliliters of cyhalothrin 2.5% missible oil, 50% acephatemet missible oil adds 1 milliliter in sesame oil for 450 milliliters, uses behind 4500 times of the dilute with waters.
