Abstract
The present invention relates to an emulsifiable solution composition and a method of preventing and killing various pests by applying the composition; the emulsifiable solution composition is prepared from two pesticides, 1-(methylthio) ethylidene ammonia-methyl carbamate, S-1, 2-two (ethoxy carbonyl) ethyl O, O-dimethyl phosphorothioate, a synergistic agent O, O-diethyl-O-phenylthio acid ester, an emulsifying agent and a solvent. In the two pesticides, the former belongs to a pesticide with high toxicity; when used individually, the former has high cost and does not kill red spiders; when the use concentration is slightly high, phytotoxicity is generated to cotton; the latter is an organic phosphorus pesticide with low toxicity and broad spectrum and has low medicine effect. The present invention processes the two pesticides into a mixing agent; or the synergistic agent which can enhance the medicine effect is added to make the two pesticides become broad-spectrum pesticides with high efficiency and moderate toxicity. The present invention is suitable for preventing and killing pests for various crops and has the advantages of obvious social benefit and obvious economic benefit.
Description
The present invention relates to by insecticide 1-(methyl mercapto) ethidene ammonia-methylcarbamate [to call Methomyl (methomyl) in the following text] and S-1,2-two (ethoxy carbonyl) ethyl O, O-dimethyl disulfide substituted phosphate [to call malathion (malathion) in the following text] and can improve the synergist O of insecticidal effect, the milk oil composition of O-diethyl-O-phenyl phosphorothionate [to call synergy phosphorus (SV1) in the following text] and emulsifier, solvent.
The present invention relates to prevent and treat the method for various agricultural insect simultaneously with said composition.
Methomyl is a kind of efficient, high malicious insecticide, and has the application cost height, do not kill two spotted spider mite, and dangerous to cotton when working concentration is slightly high, continuous single use causes that easily insect produces shortcomings such as resistance.
The malathion is a kind of lower toxicity organic phosphor desinsection miticide, the effect wide spectrum, and agricultural cost is lower, but does not have the inner sucting killing insect effect.
The present invention finds that Methomyl and malathion are used with, and cotten aphid, vegetable aphid, cotton bollworm etc. are had significant synergistic effect.Both are mixed by proper proportion, or add synergist in addition, can improve control efficiency significantly, reduced the toxicity of preparation, reduced use cost, improved safety, also can delay the resistance generation of insect Methomyl to cotton to various pests.With these two kinds of medicaments is that active ingredient adds auxiliary agents such as emulsifier, solvent, or adds synergy phosphorus in addition, and it is processed into this composition of missible oil.
The invention provides a kind of mixed pesticide that passes through, strengthen drug effect, reduce the consumption and the use cost of Methomyl, reduce preparation toxicity and raising method crop safeties such as cottons.
It is a kind of by using synergist to improve drug effect that the present invention also provides, and reduces the method for pesticide dosage.
The invention provides a method of using above-mentioned composition to prevent and treat various pests.
The spendable emulsifier of the present invention is: the mixed emulsifier that is made into TX-10, OR-201, QR-01 etc.
The solvent that the present invention uses comprises toluene, dimethylbenzene, methyl alcohol etc.
This composition can be processed into missible oil by traditional method.
It is as follows that the technological process of missible oil is processed in the present invention, but be not limited thereto.
Former medicine → metering →
Solvent 1+solvent 2 → measure → dissolve → go out
Crude oil 1+metering--------→ accent → material → finished product
Solvent 3 → metering--------→ system bag
Emulsifier → metering--------→ dress
The present invention is processed into missible oil and further is illustrated by following " example ", but is not limited thereto.Below all umbers all refer to weight.
10 parts of example 1 Methomyls
10 parts of malathions
15 parts in synergy phosphorus
10 parts of emulsifier
10 parts of methyl alcohol
20 parts of toluene
25 parts of dimethylbenzene
It is processed into missible oil by above-mentioned flow process.
10 parts of example 2 Methomyls
15 parts of malathions
10 parts in synergy phosphorus
10 parts of emulsifier
10 parts of methyl alcohol
20 parts of toluene
25 parts of dimethylbenzene
It is processed into missible oil by last convection journey.
10 parts of example 3 Methomyls
25 parts of malathions
10 parts of emulsifier
10 parts of methyl alcohol
20 parts of toluene
25 parts of dimethylbenzene
It is processed into missible oil by above-mentioned flow process.
Use the method for above-mentioned composition pest control to be: control cotten aphid, vegetable aphid, cigarette aphid etc., about 50 milliliters every mu.Control cotton bollworm, rice grub etc., 50～75 milliliters every mu, spraying is used.
Under above-mentioned consumption, can reach more than 90% 5～7 days lasting periods to the control efficiency of various pests.Said composition all is better than using separately the preventive effect of Methomyl and malathion to the various pests preventive effect on cotton, vegetables, fruit tree, the tobacco crop.Society and economic benefit are very remarkable.
