Abstract
The present invention is a kind of composition pesticide of killing mite class and phytophthira pest, is made up of the soluble halide of anionic surface active substances and 1 valency or divalent metallic element.
Description
What the present invention relates to is a kind of composition pesticide.
Widely used various insecticide pesticides mostly are dissimilar organic class medicines on agricultural at present.Along with the enhancing of insect to drug tolerance, amount of drug is also continuing to increase, thereby these medicines influence also in obvious increase the direct and indirect toxic and side effect of people and animals.Along with the organic agricultural chemicals of new construction, newtype is constantly developed and come into operation, not only these problems are still continuing and development, but also make drug cost also in continuous increase.Meanwhile, but day falls into neglect the insecticide that is main component with simple in structure, lower-cost inorganic compound.Present technique inventor had once introduced a kind of broad spectrum disinfestation composition pesticide of being made up of alkali compounds, halide and surface reactive material in Chinese patent CN88105934.X, because the requirement that alkali compounds is wherein arranged and keep certain alkalescence has certain limitation in some cases.
It is more simple to the purpose of this invention is to provide a kind of composition, and mite class and phytophthira pest are killed the high composition pesticide of selectivity.
Composition pesticide of the present invention is made up of the soluble halide of anionic surface active substances and 1 valency or divalent metallic element.This two parts by weight ratio is surface reactive material 0.4-2.5 part, halide 1-3 part.Form by various anionic surface activity material because common civilian synthetic detergent is many, thereby its wide material sources, generally can directly use these synthetic detergents as raw material.At said 1 valency of the present invention or divalent metallic element halide, as sodium halide, in the compounds such as potassium halide, calcium halide, the most extensively make things convenient for sodium chloride, general salt, worker's salt etc. all can be used as raw material.Above-mentioned various compositions all are water miscible, and therefore when using agricultural chemicals of the present invention, as required with getting final product after an amount of water-soluble the separating, the aqueous solution that for example can be made into 0.8-1.3% generally speaking sprays.
Through repetition test with observe to find, use agricultural chemicals of the present invention after, mite pest can be dead in 10-30 minute, killing rate is that 96-99%(U.S. propargite missible oil is 93-97%, dicofol is about 88%); Aphid began dead in 1 day, mortality in 5-7 days, killing rate is about 96% for the 96-98%(flolimat).The borer population rate that goes down is checked in medication after 15 days, the mite class is about 96%, with propargite missible oil quite (flolimat is about 66%); Aphid is about 93%, and is approaching with flolimat.As seen dead polypide after being killed by agricultural chemicals of the present invention is observed, and dead polypide is mostly occurred and significantly dries up and the atrophy phenomenon.Can know by inference thus, agricultural chemicals of the present invention makes the reason of insect death except that it is generally acknowledged that surface reactive material is attached to the polypide surface and can causes the smothering action, wetting and the adhesion property that surface reactive material is good makes the halide composition adhere to the polypide surface effectively, make the dehydration of polypide cell by halid osmotic pressure, having destroyed its cell structure also is an important factor, thereby these insects are had good killing effect.
Owing to do not contain the Acidity of Aikalinity composition in the insecticide pesticide of the present invention, acid-base value during to use does not have specific (special) requirements yet, therefore when mite class and phytophthira pest are had higher killing rate, also avoided requiring inconvenience and the harmful effect brought because of acid-base value, and because composition is simple, raw material is extensively cheap and easy to get, has also further reduced drug cost.
What introduce below is some instantiations as foregoing of the present invention.
In these examples, surface reactive material select for use with neopelex or by sodium phosphate trimer be composition the normal domestic synthetic detergent all can, halide is representative with sodium chloride (salt or worker's salt).The composition of each example sees the following form
