Abstract
The effervescent pesticide composition is a new formulation for integrated control of plant diseases and pests, and its formulae included by said invention are respectively formed from the active components of different pesticides, effervescent agent, filler, dispersing agent, moistening agent, disintegrating agent and specific gravity regulating agent, in which the kind of specific gravity regulating agent and its dosage can determine the floating property of said granules in water. This floating property can ensure that the pesticide granules can be fully dispersed in water. Said invented granular formulation can be made up by conventional granulating process, and features accurate dosage, small package volume and convenient use, storage and transportation.
Description
The present invention relates to a kind of effervescence farm-chemical composition that is used for the extermination of disease and insect pest, particularly effervescent.
The packing that present domestic most Pesticidal products are pressed powder or liquid, packing, preservation, use are very inconvenient, make granule and then can address the above problem well, make effervescent granule is dissolved more apace.
CN1069850A discloses a kind of tablet that is used for the agrochemistry of paddy field, and it comprises pesticide activity component, effervescent agent, water-soluble polymer and waterproofing agent; CN1074083A discloses a kind of tablet formulation that contains internal desiccant, and it comprises pesticide activity component, effervescent agent, dispersant, wetting agent, disintegrant and internal desiccant.
The present invention provides a kind of method that contains the effervescent agricultural chemicals of proportion conditioning agent, compare with pulvis, liquor have packing, preservation, the more convenient characteristics of use, and moisture absorption is decomposed slow in air, but after in the input water again very easily disintegration dissolve, discharge active principle, do not influence result of use.
The invention provides effervescence farm-chemical composition, particularly a kind of effervescent, it comprises agricultural chemicals, effervescent agent, dispersant, wetting agent, disintegrant, proportion conditioning agent and filler.Its solvent consists of:
(ⅰ) agricultural chemicals of about 0.05-80%;
(ⅱ) decentralized system of about 20-99.95% wherein specifically consists of:

Effervescent agent is the compound of a carbonate or bicarbonate and solid, water soluble acidic materials.In the aqueous medium that does not use effervescent agent, actual can not the acquisition of the tablet of water-fast active component decomposed rapidly basically.The saline and alkaline reaction of organic acid plus carbonate or bicarbonate provides the carbon dioxide gas that helps in this respect.Carbonate or bicarbonate are meant carbonate or bicarbonate or its mixture of ammonium, lithium, sodium or potassium; The solid, water soluble acidic materials, inorganic acid material or organic acid all can.The inorganic acid material includes but not limited to: phosphate or acid condensed phosphate, organic acid include but not limited to carboxylic acid or contain oxycarboxylic acid, as oxalic acid, succinic acid, adipic acid, fumaric acid, tartaric acid, Citric acid, malic acid, gluconic acid or maleic acid.
Adding dispersant is for particle or the missible oil that makes the active component that forms in the granule disintegrating procedue still keeps released state in cold hard water, thereby is easy to form dispersion liquid and suspension, available anionic dispersing agents or non-ionic dispersing agent.Anionic dispersing agents includes but not limited to alkylnaphthalene sulfonate, the salt of two (alkyl) naphthalene sulfonic acid-formaldehyde condensation product, naphthalene sulfonic acid-formaldehyde condensation product sodium salt, alkyl naphthalene sulfonic acid formaldehyde condensation products etc.; Non-ionic dispersing agent includes but not limited to alkylphenol polyoxyethylene, aliphatic amine polyoxyethylene ether and fatty acid amide APEO, polyoxyethylene carboxylate, vegetable oil ethylene oxide adduct and derivative etc.
Wetting agent can reduce the surface tension between bubble and the solid particle agent, thus form be easy to shift out from the granule surface than minute bubbles; When spraying, can increase pastille liquid again to handling the contact of the object surface of solids, make the wetting or acceleration wet processes of its energy.It comprises anionic or nonionic surface active agent, and it comprises and is not limited to alkyl sulfate, alkylsulfonate, alkylaryl sulfonate, alkylphosphonate, polyoxyethylene alkyl ether, polyoxyethylene alkyl aryl ether, poly-(alkylidene) glycol or ligninsulfonate.
Disintegrant makes water become swelling action to infiltrate in the granule by wicking, can include but not limited to polyvinylpyrrolidone, sodium carboxymethylcellulose, hydroxypropyl cellulose and the water-soluble conventional tablet disintegrant of energy.Common starch or cellulose base disintegrant are unsuitable for spraying, because they generally form gel on 50 order nozzles sieve, directly sow but can be used for paddy rice.In addition, also can use water-fast crosslinked polyvinylpyrrolidone.
The proportion conditioning agent can be selected for use by the required of reality, and with the proportion of control tablet, purpose is the purposes according to different granules, selects to be manufactured on the granule of the different floatation characteristics of tool in the water.As the floating particle agent that paddy field can be selected low-gravity (less than 1) for use with weed killer herbicide, then selecting for use of generally being used to spray can sink to water-bed big proportion granule (proportion is greater than 1).Can select for use the proportion conditioning agent to be divided into two classes, a class is a mineral filler, and it includes but not limited to clay and talcum powder, and another kind of is the foaming organic polymer, and it includes but not limited to wood chip and polystyrene.
Packing agent mainly comprises the carrier of the former medicine of adsorbable liquid, and it includes but not limited to white carbon, diatomite, bentonite, precipitated calcium carbonate, clay, talcum powder, kaolin etc.
Granulation adopts conventional prilling to realize that these technologies include but not limited to extruder grain, cylinder granulation etc.Mixture should be handled through super-dry before granulation, makes water content less than 0.5%.
The preparation method of composition pesticide
Formula components is generally for example ground in gas grinding machine or the hammer-mill in grinder and is mixed, and is extruder grain then, plastics package.
