Description
Technical field
The present invention relates to agricultural insecticide technical fields, and in particular to a kind of water dispersible of avermectin containing cartap bubble
Effervescent tablet.
Background technology
Cartap is usually made hydrochloride, and appearance is white crystals, there is slight cacosmia taste.M.p.183~183.5 DEG C (point
Solution) (active compound fusing point is 179~181 DEG C).It is slightly soluble in methanol, is insoluble in ethyl alcohol, insoluble in acetone, ether, chloroform, hexane, benzene
Equal organic solvents；Solubility at 25 DEG C in water is 200g/L.Stablize in acid medium, it is unstable in alkaline medium.
Stored at 40 DEG C and 60 DEG C 3 months it is unchanged, it is closed under room temperature to preserve unchanged, slightly hygroscopicity, have corrosion to metals such as iron
Property.Its free alkali molten point is 130.5~131 DEG C.
Sandworm toxin insecticide, have it is strong tag and stomach poison function, it invades the engaging portion of nerve cell, retardance
Acetylcholine secreted by previous nerve cell is communicated to latter nerve cell, and makes nerve cell that excited phenomenon not occur, makes
Insect neural paralysis cannot nibble food, cannot take action, and stop development, so that dead.There is good preventive effect to striped rice borer and pink rice borer,
And simultaneous rice leaf roller, leafhopper, armyworm etc. can be controlled, it is also effective to diamondback moth, striped flea-beetle.Rice-stem borer, yellow rice borer are used
50% 1000~1500 times of soluble powder liquid is sprayed, to 1000 times of rice plant skipper, rice leaf roller medicine liquid sprays, to duckweed snout moth's larva,
Duckweed ash snout moth's larva, diamondback moth, striped flea-beetle, phyllocnistis citrella stainton, onion thrips etc. are sprayed with 1000 times of liquid.
Avermectin has stomach toxicity and action of contace poison to mite class and insect, is unable to ovicidal.Mechanism of action and general insecticide
The difference is that nervous physiology activity is interfered, stimulation release γ-aminobutyric acid, and aminobutyric acid has the nerve conduction of arthropod
Inhibiting effect.There is paralysis symptom in mite class adult, nymph and insect larvae after being contacted with avermectin, inactive, not feeding,
It is dead after 2~4 days.Because not causing insect rapid dehydration, so avermectin lethal effect is slower.Avermectin is to predatism
Though insect and insect parasite have direct action of contace poison, because plant surface residual is few, therefore to the damage very little of beneficial insect.Avermectin
Element will not be moved in soil by adsorption by soil, and be decomposed by the microorganisms, thus in the environment without cumulative function, can be used as comprehensive
Close a component part of prevention.Modulation is easy, and can be used slightly being stirred in the preparation water of falling people, also safer to crop,
Poisoning will not occur by the method use of introduction.Applicable crops vegetables, citrus, cotton etc..
The primary pest of south China rice has homoptera pest (planthopper) and lepidoptera pest (rice clump leaf roll snout moth's larva, two
Change snout moth's larva, yellow rice borer) etc., above-mentioned cartap, avermectin two kinds of insecticides exclusive use cannot prevent completely rice grub it
Purpose.
Cartap and avermectin mixture there is into apparent synergistic effect to the primary pest for preventing rice, especially to rice
The pests significant effects such as planthopper, rice clump leaf roll snout moth's larva, rice-stem borer, yellow rice borer, sugarcane cotton aphid, phyllocnistis citrella stainton, the hair
The bright pest that can be used for preventing the crops such as rice, sugarcane, fruit tree, vegetables, and plant protection cost is relatively low.
Chinese patent CN107668055A discloses a kind of anti-fatigue health-caring biscuit and preparation method thereof at present, and biscuit is under

Behind garden, required fertilizer is applied, turns over, level land, start at, is colonized cucumber.Medicament is uniformly dissipated by corresponding dose and imposes on root
In department enclosure soil.
Investigation method：30 days after dispenser, in 15 plants of cucumber of each cell random searching, root is dug out, diseased plants at different levels are recorded
Number calculates diseased plant rate, disease index and control effect, and carries out variance analysis to preventive effect, is respectively handled with newly multiple differential method
Between the significance of difference.Diseased plant stage division：
Severity Scaling is carried out by following standards：Disease index and relative control effect is calculated by formula.
0 grade complete for root system, no root knot；
1 grade is less than 25% to there is a small amount of root knot, with necrosis；
2 grades account for the 26%~50% of root system number for root knot number；
3 grades account for the 51%~75% of root system number for root knot number；
4 grades special more and larger for root knot, account for the 76%~100% of root system number
Disease index=Σ (the plant number * at different levels values of series)/(total strain number * 4) * 100
Control effect (%)=(control disease index-processing disease index)/control disease index * 100
It the results are shown in Table 1
