Abstract
The present invention relates to an emulsifiable solution composition and a method for preventing and killing cotton insects by applying the composition; the emulsifiable solution composition is prepared from two pesticides, 1-(methylthio) ethylidene ammonia-methyl carbamate, O, O-dimethyl-O-(dinitrophenylation) sulfur phosphate, a synergistic agent, O, O-diethyl-O-phenylthio phosphate, an emulsifying agent and a solvent. In the two pesticides, the former is individually used, has high cost and does not kill red spiders; when the use concentration is slightly high, medicine damage can be generated to cotton; the latter has high toxicity. The present invention processes the two pesticides into a mixing agent; the synergistic agent which can enhance the medicine effect is added to make the two pesticides become efficient medicine for preventing and killing cotton insects. The present invention has the advantage of obvious social and 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 O, O-dimethyl-O-(right-nitrobenzophenone) phosphorothionate [to call methyl one or six O five (Parathion-methyl) in the following text] and can improve the synergist O of insecticidal effect, O-diethyl-O-phenyl phosphorothionate is [to call synergy phosphorus (SV in the following text
1)] and the milk oil composition of emulsifier, solvent.
Simultaneously, the present invention relates to prevent and treat the method for cotton-plant pest-insects with said composition.
Methomyl is a kind of efficient, hypertoxic type insecticide, use cost height, dangerous when cotton red spider and working concentration are slightly high extremely to cotton, and in addition, the continuous use can cause that insect develops immunity to drugs singlely.
Methyl one or six O five are a kind of hypertoxic type insecticides, and insecticidal spectrum is wide, and use cost is lower.
The present invention finds, Methomyl and methyl one or six O five use with, cotten aphid, cotton bollworm there is significant synergistic effect, both are mixed by proper proportion, and add synergy phosphorus, and can improve control efficiency significantly to cotton-plant pest-insects, reduce use cost, raising also can delay the resistance generation of cotton-plant pest-insects to Methomyl to the safety of cotton.With these two kinds of medicaments is active ingredient, adds synergist, emulsifier and organic solvent, and it is processed into this composition of missible oil.
The invention provides a kind of use synergist that passes through and improve effect of chemical control, thereby reduce medicament effective dose and the method for raising Methomyl cotton safety.
The invention provides one in the control cotton-plant pest-insects, use the method for above-mentioned composition.
The mixed emulsifier of the operable emulsifier of the present invention for being made into TX-01, OR-201 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---→ go out
Solvent 1+ solvent 2 → metering → dissolving → accent → material → finished product
Crude oil → metering---------→ system bag
Emulsifier → metering------→ dress
Solvent 3---------→
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
5 15 parts of methyl one or six O
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.
5 parts of example 2 Methomyls
5 15 parts of methyl one or six O
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.
Use the method for above-mentioned composition control cotten aphid to be: cotton in seedling stage, every mu is used about 30 milliliters, and the cotton growth middle and later periods, about 50 milliliters every mu, spraying is used.The method of control cotton bollworm is: the control second-generation cotton bollworm, and 40 milliliters every mu, control three, four generations of cotton bollworm, about 80 milliliters every mu, spraying is used.
Under above-mentioned consumption, can reach more than 90% the control efficiency of cotten aphid, 5～7 days lasting periods, can reach more than 85% 5～7 days lasting periods to the control efficiency of cotton bollworm.Said composition all is better than Methomyl and methyl one or the six O five independent effects of using to the control efficiency of cotten aphid, cotton bollworm, is to prevent and treat one of efficient medicament of cotton-plant pest-insects at present, society and remarkable in economical benefits.
