Description
Technical field
The present invention establishes and a kind of micro-emulsion insecticide of preventing and treating rice grub, particularly a kind of can be at the wetting spread of paddy rice leaf surface, slow down the synergistic avermectin microemulsion of photodissociation.
Background technology
Avermectin is that a class that Japanese Kitasato Kenkyusho (JP) 9-1, Shirokane 5-chome, Minato-ku, Tokyo 108, Japan and Merck company at first develop has desinsection, kills ten hexa-atomic Macrocyclic lactone compounds of mite, eelworm-killing activity, extracts the metabolite that separates by streptomycete (Streptomycesavermitilis) fermentation back.Avermectin put goods on the market as agricultural chemicals in 1985, and up to the present, Avermectin control spectrum comprises that insects such as Acarina, coleoptera, Homoptera and Lepidoptera, the evil mite in the arthropods has 84 kinds more than at least.This insecticide utmost point is insoluble in water, and commercially available majority is the missible oil formulation, and aromatic solvent wherein exists that environmental pollution is serious, poisoning is big, produce the uneasy congruent shortcoming of storing, has limited use in some countries.10mg/L registration amount with Avermectin control diamond-back moth and beet armyworm in the agricultural chemicals electronic documentation of the Ministry of Agriculture is reference, the Avermectin preparation that China produces is when concentration is 10mg/L, the surface tension of its solution all is far longer than the critical surface tension 36.7mN/m of paddy rice, be difficult to wetting spread on rice leaf well, most soups that spray tumble with the form of drop, reduced the probability that insect contacts with soup, most of soups flow in the environment, increased the degraded pressure of environment, polluted environment, the huge waste that has caused resource is (referring to document 1, " some soup difficulties are in paddy rice; the analysis of causes of wheat and the wetting spread of wild cabbage " Pesticide Science journal, Vol.4 No.2 (2002) is p.75-80).Simultaneously, Avermectin sees that light can decompose rapidly by oxidation and photooxidation mechanism, and under the simulated solar irradiation, the photodissociation half life period is about 18.84h-59.24h, and the light degradation half life period is 12h in the water; In soil, the illumination degrading half life period be 21h (referring to document 2, " Determination of sunscreen compounds in tropicalsunscreen product " Chromatoggraphy, Vol.519 (1999), p.117-124; Document 3, " synergistic effect that ultraviolet absorber suppresses the Avermectin photodissociation and diamond-back moth is prevented and treated " ecological magazine, Vol.25 No.2 (2006), p.185-188).Be the peak period of paddy rice medication August-October, Avermectin uses the back to form the medicine film, under solar light irradiation, (be mainly ultraviolet ray), improved the photodissociation speed of Avermectin greatly, make that the land for growing field crops lasting period short, increase peasant's medication number of times and unit control cost virtually, thereby cause it to promote difficulty in the land for growing field crops.
Avermectin is a kind of biopesticide, induces insect to develop immunity to drugs than chemical pesticide is easier.In agricultural chemicals, add in general mineral oil, azone, outstanding imitate sharp or other surface tension synergist help improving soup to the insect cuticle penetrance (referring to document 4, " bleeding agent is to beta-cypermethrin virulence and three kinds of Ultrastructural influences of lepidoptera pest epicuticle " insect journal, Vol.51No.2 (2008), p.216-221; Document 5, " 3 kinds of auxiliary agents are to the synergistic effect of beta-cypermethrin " Jiangsu agricultural journal, Vol.24 No.6 (2008) p.820-825), thereby reduces dosage, improves control efficiency, and helps overcoming the pesticide resistance that insect produces medicament.Simultaneously very easily add light stabilizer in the agricultural chemicals of photodissociation, reduce the decomposition rate after Avermectin forms the medicine film, delay the rate of release of Avermectin, thereby improve the photostability of Avermectin preparation, improve drug effect in Avermectin etc.
Critical surface tension is the most important empirical parameter that characterizes low-energy solid moistened surface character, as long as surface tension be equal to or less than the liquid of critical surface tension could be on this solid spontaneous sprawling (referring to document 4, " surfactant science and application " p.193-223).Surfactant can reduce the surface tension of liquid, and the surfactant concentration in the soup that field spray uses must just can make droplet be held by the blade face rapidly above critical micelle concentration and stay.This just requires to select and rationally uses surfactant, surface tension synergist, light stabilizer, Avermectin and water are mixed equably, form stable water oil-packaging type micro-emulsion agent, simultaneously its photostability strengthens, surface tension is less than the critical surface tension of paddy rice, and the surfactant in the soup is greater than critical micelle concentration, so that can be on paddy rice wetting spread, increase the liquid holdup of rice leaf, under the prerequisite that reduces consumption of organic solvent and effective ingredient consumption, improve drug effect.
Up to the present, do not see that be used on the paddy rice can wetting well rice leaf, the preparation that can delay the Avermectin photodissociation simultaneously again comes out.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiencies in the prior art, and a kind of sustained-release synergistic avermectin microemulsion that is used for paddy rice is provided, and realized modularization pipe row.
The technical solution adopted for the present invention to solve the technical problems is as follows: a kind of sustained-release synergistic avermectin microemulsion that is used for paddy rice is characterized in that being combined by its mass ratio by following component:
The component mass ratio
Avermectin: 1%-5%,
Organic solvent: 10%-40%,
Calcium dodecyl benzene sulfonate: 0.8%-2.5%,
Alkylphenol-polyethenoxy (10) ether: 1%-5%,
Polyoxyethylene (20) sorbitan fatty acid ester: 1%-7.5%,
Surface tension synergist: 1.5%-5%,
Light stabilizer: 0.4%-2%,
Antifreezing agent: 1%-2%,
Dilution water: surplus,

20-30 ℃ of photolysis chamber control room temperature, adopt the artificial light source uviol lamp to shine, carry out sample detecting respectively at irradiation back 1h, 2h, 4h, 8h, 16h, 24h.As can be seen from Figure 1 the photodissociation of Avermectin meets first _ order kinetics equation, C
t=76.881e
-0.1708t(R
2=0.9969), the photodissociation half life period is 2.46h, and the photodissociation process of adding light stabilizer 1 and light stabilizer 2 also meets first _ order kinetics equation, and its equation is respectively C
t=79.093e
-0.0841t(R
2=0.9940), the photodissociation half life period is 3.17h and C
t=89.622e
-0.0494t(R
2=0.9957), the photodissociation half life period is 3.70h.The interpolation of light stabilizer makes the photodissociation half life period of Avermectin prolong 28.86% and 50.41% respectively.
Fig. 2 is the coordinate diagram that concerns that the method for surfactant critical micelle concentration and the mensuration critical surface tension value that proposes according to Zisman is measured the paddy rice critical surface tension in the surface tension, soup of the synergistic avermectin microemulsion variable concentrations soup of the present invention measured according to the method for GB-5549-90.
As can be seen from Figure 2, when AVM concentration is 8.91mg/L, the table in the microemulsion soup Surface-active agent has reached critical micelle concentration. Therefore as long as the concentration of avermectin micro-emulsion of the present invention is big In 8.91mg/L, the surfactant concentration in the soup has just surpassed critical micelle concentration, and soup Surface tension less than the critical surface tension of rice leaf. The AVM concentration of recommendation of the present invention 9mg/L one 90mg/L, soup this moment wet spreading well on rice leaf can be given full play to Drug effect can be saved medication again.
Embodiment
With reference to the accompanying drawings and in conjunction with example the present invention is described in further detail.But the invention is not restricted to given example.
The present invention provides composition embodiment 1-12, referring to table 1-table 4, wherein the surface tension synergist is mixed by first boosting components, second boosting components, first boosting components is the outstanding profit of imitating, second boosting components is one or both of mineral oil, azone, and the mass ratio of first boosting components and second boosting components is 0.5~9: 1.
The present invention gives avermectin micro-emulsion and the comparison (table 5) of holding dose of abamectin emulsifiable concentrate on rice leaf, as can be seen from the table the concentration of 1.8% avermectin micro-emulsion 5.63mg/L-90mg/L on the paddy rice hold dose all the utmost point be significantly higher than 1.8% abamectin emulsifiable concentrate 10mg/L and on paddy rice, hold dose.Table 6, table 7 be respectively 1.8% avermectin micro-emulsion to rice-stem borer and 5% avermectin micro-emulsion to the drug effect of rice leaf roller relatively (converting water 750kg spray application) by per hectare, therefrom the avermectin micro-emulsion drug effect of testing used dosage all is better than abamectin emulsifiable concentrate as can be seen.
