Abstract
An agricultural Chemical for preventing and eliminating rice plant hopper, leafhopper, etc. is prepared from buprofezin (1-20 Wt.%) solid or liquid carrier (60-95 wt%), emulsifier (2-20 wt%), developer (0.1-10 wt%), codeveloper (0-10 wt%) and penetrant (0-8 wt%) through mixing, homogenizing and regulating content of active components, water content and pH to 5-7. Its advantages include quickly taking its effect and high effect.
Description
The present invention discloses and a kind ofly both can be used for artificial sprinkling, can splash into the water surface again and launch and climb along plant the agricultural chemical ' pushi ' preparation that covers automatically at the water surface.
In recent years, American-European and Japan has delivered many patent and papers about water surface leafing agent.These patents and paper only limit to the research of solid granular leafing agent, can be divided into following a few class substantially: (1) does carrier with the water-soluble solid material, after medicament imposes in the water, this water-solubility carrier dissolves rapidly, and promote active component and spread at the water surface in company with the residual carrier material, as JP60142901, JP813090; (2) do carrier with the shipwreck dissolved matter, apply one deck hydrophober and be aided with solvent, make granula floating and be scattered in the method for the water surface automatically, as JP481181, JP471240, JP49242225, JP45966205, JP5826882 etc. at carrier surface; (3) do carrier with the mixture of slightly water-soluble material and water-soluble substances, when this granule was granted in the water, rapid dissolving of this water-soluble substances and promotion were bubbled through the water column attached to the pesticide activity component on the slightly water-soluble material and are spread, as CN88102168; (4) 96101003.7 of Chinese patent application have been introduced a kind of liquid water surface leafing agent, and said preparation can directly splash into the water surface and diffusion rapidly, and enter in the plant body through scattering and permeating, thereby play the effect of control plant damage by disease and insect.All there is defective to some extent in above prior art, and main the performance in the following areas: when (1) did carrier with the slightly water-soluble material, to having relatively high expectations of carrier material, dissolution velocity must be very fast, otherwise is difficult to promote former medicine diffusion.If before soil surface, dissolve fully, then can cause the availability decline of former medicine to the suction-operated of agricultural chemicals because of soil particle at particles settling; (2) do carrier with slightly water-soluble porous adsorbent, then can reduce the availability of former medicine to the suction-operated of pesticide activity component because of carrier material; (3) existence and (1), (2) identical problem, and after water-soluble substances is molten entirely, can easily can not floated the water surface owing to particle becomes by water-wet, can only be dispersed in the water body, make active component can't in time be released to the water surface; (4) above preparation all is confined to use in water body, can't use when the lack of water of rice field, and in addition, these preparations also require to keep in the rice field a certain amount of water of certain hour when using, otherwise will have a strong impact on the result of use of agricultural chemicals; (5) conventional formulations such as pulvis, missible oil, colloidal suspending agent, suspending agent can only adopt the mode dispenser of artificial sprinkling, the same with the floating autgmentability pesticidal preparations of the water surface, insecticide-applying way is single, efficiency is low during the conventional formulation dispenser, and the drug effect of the floating autgmentability pesticidal preparations of the water surface then is subjected to the field water quantitative limitation.
The objective of the invention is deficiency at existing pesticidal preparations existence, a kind of restriction that promptly is not subjected to insecticide-applying way is proposed, can rapidly active component be administered on the plant again, fast and effeciently prevent and treat the multi-functional buprofezin pesticidal preparations of insect pests such as rice fulgorid, leafhopper, aleyrodid.
For reaching above purpose, the technical solution used in the present invention is: a kind of buprofezin pesticidal preparations is characterized in that: (1) is mixed into the homogeneous system with buprofezin active component 1.0-20.0wt% and solid-state or liquid carrier material 60-95.0wt% under 30～100 ℃; (2) and then in above-mentioned isotropic body is add floating agent 2-20.0wt%, solvent 0.1-10.0wt% launches auxiliary agent 0-10.0wt%, bleeding agent 0.1-8.0wt%, and the control temperature mixes into the homogeneous system at 30～50 ℃; (3) adjust active constituent content, moisture≤0.5wt% and pH value 5-7 promptly get component A; (4) with emulsifier 1-20wt%, solvent 1-10.0wt% launches auxiliary agent 0-8.0wt%, bleeding agent 0-5.0wt%, and be mixed into the homogeneous system, promptly get B component; (5) component A can use separately, also can be used in combination with B component.
Solid-state carrier material of the present invention is meant ease of solubility solid matters such as ammonium salt, sylvite, sodium salt; Liquid carrier is meant slightly solubility organic matters such as ethene, acetonitrile, dichloroethane, cyclohexane, toluene, dimethylbenzene.Emulsifier is meant cationic surfactant, anion surfactant, non-ionic surface active agent, the amphoteric surfactant of HLB value between 5-20.Solvent is meant that the HLB value is at solid-state or liquid anion surfactant, non-ionic surface active agent, amphoteric surfactant more than 8.Launch auxiliary agent and be meant ammonia salt, alcohols, metallic salt etc.
The present invention both had been different from conventional formulations such as pulvis, missible oil, colloidal suspending agent, suspending agent, be different from again can free-floating in water surface, pesticide activity component wherein can by evapotranspire and to the infiltration of plant and conduction and effectively control live on the water surface or the above plant of the water surface on pest, pest on plant has special-effect than conventional formulation and application method near the water surface or the water surface to living in for it.
The present invention has advantage: 1. insecticide efficiency height, instant effect; 2. both can be used for artificial sprinkling, and can directly drip again, be sprinkled into the water surface and diffusion automatically; 3. can climb along plant and cover the biology on the direct killing plant; 4. preparation is not subjected to the plant strain growth environmental limit, and no matter the water yield all can be used, and insecticide-applying way can be adjusted as the case may be; 5. no matter still all have impayable advantage and application prospect than conventional formulation in the very high place of mechanization degree on the labor intensive farm.
