Abstract
The present invention discloses an agricultural chemical 'Bensulfuron-methyl' preparation which can be directly dropped or sprayed on the water surface to quickly release pesticide activity components and automatically expand on the surface to climb and cover along plants. 0.01 to 5.0 wt% of active components of 'Bensulfuron-methyl' of the present invention and 60 to 90.0 wt% of solid or liquid carrier materials are uniformly mixed; 0.5 to 12 wt% of developing agents, 0.1 to 10.0 wt% of developing auxiliary agents and 0.01 to 15.0 wt% of penetration promoters are added in a mixture obtained by the steps to be mixed into a homogeneous system; the content of effective components is regulated: the moisture content is less than or equal to 0.5 %wt, and the PH value is from 5 to 7.
Description
The present invention discloses a kind ofly both can directly have been dripped or be sprinkled into the water surface and discharge the pesticide activity component rapidly, can launch and climb along plant the bensulfuron-methyl pesticidal preparations that covers automatically at the water surface.
Bensulfuron-methyl pesticidal preparations provided by the present invention is 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 the floating autgmentability pesticidal preparations of the common water surface of pest.At present, the international research direction in this area, 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 solid matter and water-soluble solid material, when this granule imposes in the water, rapid dissolving of this water-soluble substances and promotion are 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, said preparation is that carrier can directly splash into the water surface and diffusion rapidly with the slightly water-soluble organic liquid, and enter in the plant body, thereby play the effect of control plant damage by disease and insect through scattering and permeating.All there is defective to some extent in above prior art, the main performance in the following areas: all be limited to solid material in above-mentioned (1), (2), (3) class scheme and make carrier, (4) then be limited to the slightly solubility organic liquid and make carrier, when doing carrier with the slightly water-soluble material, to having relatively high expectations of carrier material, dissolution velocity must be very fast, otherwise be 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; 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; In addition, the prepared pesticidal preparations seepage velocity of above prior art is slow, and desinsection or weeding ratio are low.
The objective of the invention is the deficiency that exists at existing pesticidal preparations, propose that a kind of diffusion velocity is fast, high osmosis, the bensulfuron-methyl pesticidal preparations that weeding ratio is high.
For reaching above purpose, the technical solution used in the present invention is: a kind of bensulfuron-methyl pesticidal preparations is characterized in that: with bensulfuron-methyl active component 0.01-5.0wt%, solid-state or liquid carrier material 60-90.0wt% mixes (1); (2) with solvent 0.5-12wt%, launch auxiliary agent 0.1-10.0wt%, penetration enhancer 0.01-15.0wt% joins in the mixture of (1) step gained and is mixed into homogeneous system; (3) adjust active constituent content, moisture≤0.5%wt and pH value 5-7.
Solid-state carrier material of the present invention is meant easily dissolubility solid matter such as ammonium salt, sylvite, sodium salt, urea; Liquid carrier is meant slightly solubility organic matters such as methyl alcohol, acetonitrile, carrene, acetone, ethyl acetate, cyclohexane.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 be meant ammonia salt, alcohols, organic acid and HLB value at the moon more than 15 from superficiality agent, non-ionic surface active agent, amphoteric surfactant etc.
Bensulfuron-methyl pesticidal preparations provided by the present invention is 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 the floating autgmentability pesticidal preparations of the common water surface of pest.
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 the floating autgmentability pesticidal preparations of the common water surface of 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: prevent and treat efficient height, instant effect 1.; 2. can directly drip or be sprinkled into the water surface, the active constituent rate of release is fast, and getting development rate at the water surface, can to reach the distribution of 0.05-0.30m/s on the water surface even fast; 3. can climb along plant and cover, effectively kill and wound multiple weeds; 4. can be made into solid formulation, also can be made into liquid formulation, also have good fertilizer efficiency when adopting sylvite or ammonium salt to make carrier; 5. can raise labour efficiency greatly; 6. when using in the high area of automaticity, has more wide application prospect than conventional formulation.
