Abstract
The present invention discloses an IPP suspension. Its composition includes (by wt%) 5%-50% of IPP, 1%-10% of defoaming agent, 0.5%-50% of dispersing agent, 0.1%-5% of antifreezing agent, 0.3-10% of thickening agent, 0.01%-20% of stabilizing agent, 0%-10% of penetrating agent and 10%-80% of water. Besides, said invention also provides its preparation method. Said IPP suspension has good insecticidal effect.
Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of suspending agent that contains insecticide active substance and preparation method thereof.
Background technology
The present invention is that to be developed into water be the suspending agent of solvent, and has stronger insecticidal activity.
IPP chemical name: 1-(6-chloro-3-picolyl)-8-nitro-7-methyl isophthalic acid, 2,3,5,6,7-six hydrogen imidazos [1,2-a] pyridine-5-alcohol (hereinafter to be referred as IPP).
IPP is the efficient insecticide active substance, and it is to environment, people, animal, pest natural enemy and other beneficial organism safety, and antagonism rice fulgorid preventive effect is better, is eco-friendly insecticide active substance, at present also untapped this product in countries in the world.In recent years, the modern formulations of pesticide environmental protectionization of national requirements, the formulations of pesticide are to water baseization, ultramicronising, no dust and the development of sustained release aspect.Wherein water baseization is exactly one of main direction of agricultural chemicals development.Water can reduce the consumption of organic solvent as the suspending agent of solvent, the dust pollution that does not have wetting powder and pulvis to bring again, and reduced the pesticide producing cost, become a kind of very important formulation in the pesticide manufacturing.
Summary of the invention
The objective of the invention is the IPP powder to be dispersed in the water with small solid state, a kind of consumption that can reduce the organic solvent in the pesticidal preparations is provided, thereby protects the suspending agent of IPP better by the effect of dispersant and the physics peptizaiton of ball mill.
Another object of the present invention provides a kind of preparation method of above-mentioned suspending agent.
Purpose of the present invention can reach by following measure:
A kind of IPP suspending agent, form by following components in weight percentage:
IPP 5%～50% defoamer 1%～10%
Dispersant 0.5%～50% antifreezing agent 0.1%～5%
Thickener 0.3～10% stabilizing agent 0.01%～20%
Bleeding agent 0%～10% water 10%～80%.
Dispersant is selected from one or more in sodium lignin sulfonate, lignin calcium iodate, lauryl alcohol polyethylene glycol oxide base ether sodium sulfate, alkyl naphthalene formaldehyde condensate sulfonates, neopelex or the lauryl sodium sulfate.
Thickener is selected from one or more in xanthans, CMC, hydroxyethylcellulose or the methylcellulose.
Bleeding agent is a Laurocapram.
Defoamer is silicone oil or silicone.
Antifreezing agent is selected from one or more in ethylene glycol, glycerine, propane diols or the polyethylene glycol.
Stabilizing agent is selected from one or more in catechol, butyl glycidyl ether, phenyl glycidyl ether, cresyl glycidyl ether, polyethylene glycol diglycidyl ether, chloropropylene oxide, sodium sorbate or the Sodium Benzoate.
Wherein water is preferably used deionized water.
A kind of method for preparing the IPP suspending agent mixes in proportion the former powder of IPP and dispersant, thickener, stabilizing agent, defoamer, antifreezing agent, bleeding agent and water, ball milling is 2.5～3 hours in ball mill, makes particle diameter all below 5um.
Conventional dosage forms is based on EC (emulsifiable concentrate), WP (wetting powder), and water baseization formulation came into the market successively in nearly 2 years, and suspending agent (SC) then is representative wherein.Because it is a matrix with water, particle diameter is generally 1～3um, average 90% particle diameter≤5 μ m, and suspensibility 〉=90%, high the opening up and adhesivity of performance on the crop blade face, it uses drug effect to compare with WP, and very big difference is arranged.
IPP is scattered in the water with the particle of miniaturization, thereby has:
1. the flash-point height does not burn and does not explode, and produces storage and safe in utilization;
2. dust is few, and environmental pollution is little, to the producer and user and Environmental security;
3. with water matrix, aboundresources, product cost is low, easily packing;
4. said preparation suspensibility height after the spraying, is distributed in crop surface with fine particle, good disinsection effect.

1.3 test method
Establish 3 processing altogether, each is handled and repeats sub-district area 66.7m 3 times
2Local rice field four generations brown planthopper nymph peak period dispenser in 1 age on September 17th, 2006, every 667m
2Press above-mentioned design dosage to water 45kg.Aim at manually evenly complete stool spraying of rice seedling, during dispenser and behind the medicine in the week field keep water layer.
This experimental field rice varieties is for raising the spoke round-grained rice No. 7.During dispenser, field brown planthopper hundred cave worms are measured average 3476, wherein, 1 age nymph account for 98.4%.
1.4 investigation method
1.4.1 security survey
Sub-district rice seedling growing state is respectively handled in irregular observation after the dispenser, and the record rice shoot is analyzed the safety of medicament to rice seedling to the reaction or the symptom of chemical damage of medicament.
1.4.2 preventive effect effect research
Investigation insect population radix before the dispenser was respectively looked into one time the residual worm amount in field in 1,3,7,10,15 day behind the medicine.3 samplings in every sub-district, every some company looks into 6 caves, and 18 caves are looked in every sub-district.Calculate control efficiency with the insect population survival rate, computing formula is as follows:
Proofread and correct preventive effect (%)=(check plot insect population survival rate-applying area insect population survival rate) ÷ check plot insect population survival rate * 100
2 medicaments are to the safety of rice seedling
Observe after the dispenser, it is normal that each handles sub-district rice seedling growth, any poisoning situation do not occur.
3 results and analysis
10%IPPWP and 10%IPPSC have the better prevention effect to the paddy rice brown planthopper, and the Sustainable Control effect is better, to rice seedling safety.But in the performance of control efficiency, the correction preventive effect of 10%IPPSC obviously is better than 10%IPPWP, generally exceeds about 15%-20% (to see Table 1 in detail).These characteristics with SC (suspending agent) itself are associated, and can reach bigger even covering at the control target behind the suspending agent formulation thin up.Compare WP (wetting powder), the no dust of SC (suspending agent) mixes easily, and suspensibility improves, and degree of wetting also is improved.
