Abstract
The invention disclose an insecticidal and bactericidal composition containing oligosaccharins and pymetrozine, comprising the following ingredients: 1-20wt% of oligosaccharins, 1-50wt% of pymetrozine, 4-6wt% of of alkylphenol polyoxyethylene phosphate ester, 0.1-0.2wt% of organosilicon, 1-2wt% of white carbon black, 4-6wt% of glycol, 0.1-0.2wt% of sodium benzoate, 0.3-5wt% of xanthan gum, 0.6-1wt% of polypropylene carboxylic acid sodium, and the balance of water. By compounding oligosaccharins and imidacloprid, the two drug effects complement each other, the sterilization variety is enlarged, simultaneously the sterilization effect is enhanced, the application amount is low, and the composition is environmentally friendly and has high prevention rate.
Description
Technical field
The present invention relates to a kind of desinsection, bactericidal composition, relate in particular to a kind of desinsection, bactericidal composition that contains oligosaccharide element and pyrrole aphid ketone.
Background technology
Pyrrole aphid ketone belongs to pyridines or Triazinone insecticide, is developed in 1988 by Switzerland Ciba-Geigy company the earliest, and this product shows excellent control efficiency to the sucking pest of various crop.Utilizing electricity to penetrate figure (EPG) technology research shows; No matter be drop, feed or test injection, almost produce the lancet blocking effect immediately, stop to get food at once as long as aphid or plant hopper one touch pyrrole aphid ketone; And final hungry causing death, and this process is irreversible.Therefore, pyrrole aphid ketone has excellent blocking-up insect and passes malicious function.Although at present the caused lancet obstruction of pyrrole aphid ketone mechanism it be unclear that, existing research shows that this irreversible " stopping eating " is not because " food refusal effect " causes.The initial lethality of insect after pyrrole aphid ketone is handled is very low, and insect " hungry moth " still can survive a few days before causing death, and the lethality height is relevant with weather conditions.Test shows, in the chemicals treatment 3 hours, the feeding activity of aphid reduces about 90%, handles back 48 hours, and lethality can be near 100%.
Black streaked dwarf virus of rice is commonly called as " short rice ".Cardinal symptom shows as the increase of tillering, and blade is short wealthy, stiff, dark green leaf color, existing wax just on the vein of blade back and the stem stalk, the billet warty of back browning look is swelled, do not ear or fringe little, solid bad.Symptom after different growing is caught an illness is slightly variant.The lobus cardiacus poor growth of falling ill seedling stage, blade is short wide, stiff, dark green, and vein has irregular wax strumae, back blackening brown.Root is short and small, and plant is short and small, does not ear, and is often withered ahead of time.The new life that falls ill tillering stage is tillered and is shown earlier disease, stem and tiller in early days and still can extract short and small sick fringe out, but sick fringe contracts and is hidden in the leaf sheath.Shooting stage morbidity sword-like leave is short wealthy, the cripetura of fringe neck, and ripening rate is low.There is the short strip shape knurl prominent on blade back and the stem stalk.
Plant hopper is the sucking sap-sucking insect, belongs to the incomplete metamorphosis insect, and a generation has only ovum → nymph → adult.Mainly comprise brown back rice plant hopper, white-backed planthopper, small brown rice planthopper, the above two direct hazard rices cause the underproduction, and the latter mainly propagates stripe virus disease virus, mainly introduces brown back rice plant hopper and white-backed planthopper below.Brown planthopper: the long wing type of 1 adult 2 brachypterism type female adult worm 3 brachypterism type male imago brown back rice plant hopper hazard symptoms: one-tenth, nymph can both endanger, and generally are clustered in rice clump bottom, with mouthpart thorn suction rice stalk juice; Consume rice strain nutrition, moisture; And on the stem stalk, staying brown scar, spot, the secretion honeydew causes blade bituminous coal and causes other saprophytic venereal disease evils, when serious; Rice clump bottom turns black, and complete stool is withered gradually.Killed rice field is normal to occur " the yellow pool ", " wearing top " or " lice burning " earlier between Tanaka, even the field is withered entirely, is injured in early days that No kernels or seeds are gathered, as in a year of scarcity, the later stage serious underproduction of being injured.
Summary of the invention
The object of the present invention is to provide a kind of desinsection, bactericidal composition that contains oligosaccharide element and pyrrole aphid ketone, be used to prevent and treat the purposes of water rice hopper and black streak dwarf, reduced drug cost, preserved the ecological environment.
The present invention realizes like this, is made up of following weight raw material percentage: oligosaccharide element 1～20%, pyrrole aphid ketone 1%～50%, APES phosphate 4%～6%, organosilicon 0.1%-0.2%, white carbon 1%-2%, ethylene glycol 4%-6%, Sodium Benzoate 0.1%-0.2%, xanthans 0.3%-5%, polypropylene carboxylic acid sodium 0.6%-1%; All the other are water.
The plain weight ratio with pyrrole aphid ketone of oligosaccharide is preferably 20: 1 to 1: 50 in the said composition, and more preferably 10: 1 to 1: 30, most preferably 6: 1 to 1: 20.
Technique effect of the present invention is: with oligosaccharide plain with Pyraphione compound together, both drug effects are replenished each other, when enlarging the sterilization kind, have strengthened bactericidal effect, usage amount is little, and is environmentally friendly, control rate is high.
