Abstract

The invention relates to a cotton pesticide and in particular relates to a microemulsion capable of preventing and treating cotton bollworms. The cotton pesticide comprises effective components and additives, wherein the effective components comprise tolfenpyrad and allicin; the additives comprise polyoxyethylene castor oil, polyethylene glycol, acetone and capric acid. The microemulsion has a high effect of preventing and treating the cotton bollworms; by virtue of the application of tolfenpyrad and allicin, a high synergistic effect of touching and killing cotton bollworm eggs is achieved; the effect of preventing and treating the cotton bollworms is effectively improved; the cotton pesticide is high in effect, long in lasting period and free of influences on non-target crops.

Description

One grows cotton insecticide
Technical field
The present invention relates to one to grow cotton insecticide, be specifically related to a kind of microemulsion for preventing and treating cotton cotton bollworm, its active ingredient is Tolfenpyrad and allicin, belongs to technical field of pesticide.
Background technology
Cotton bollworm occur algebraically because of the time because of area and different.In Laizhou City of Shandong Province, occur 4 generations every year, the larva that grows up the last ten-days period in September descends tree to bury successively, pupates to survive the winter near nursery stock or in the soil that under weeds, 5-10cm is dark.The beginning of spring temperature go up more than 15 DEG C time start sprout wings, the first tenday period of a month in late April to May are the emergence Sheng phase, and adult occurs that the first generation is in mid or late June, and the second generation is in mid or late July, and the third generation still has cotton bollworm to occur in mid or late August to early September to early October.Adult has phototaxis, and namely dodge to join at night after emergence and lay eggs, ovum is loose to be produced, and comparatively disperses.A female moth can to lay eggs 500-1000 grain all one's life, reaches as high as 2700.Ovum fecund at leaf back, also have produce on front, plunger tip, petiole, tender stem or farming, on other plant such as weeds.Take food chorion habit after larvae hatch, newly hatched larvae has limit food habit of trooping, and two or three, three or five at face of blade or the back side, head arranges to leaf margin, inwardly takes food from leaf margin, and result blade is eaten up, only surplus master pulse and petiole, or reticulate withered, cause cured leaf.1-2 instar larvae comes downwards to ginkgo seedling terminal bud place along handle and eats from side moth or eat into into spray under terminal bud place, causes the top tip or the death of top fascicled leaves, endangers very serious.Larva before 3 ages is less, more concentrated, disperses gradually along with larval growth, enter 4 age appetite increase, edible smooth blade, only surplus petiole.Larva to be caused harm and to contain most July-August.Cotton bollworm has the habit of transfer harm, and a larva can endanger many seedlings.
Tolfenpyrad, chemical name is 4-chloro-3-ethyl-1-methyl-N-[4-(p-tolyl oxygen base) phenyl] pyrazoles-5-acid amides, Tolfenpyrad is pyrazole heterocycle class insecticidal/acaricidal agent, its main mechanism is the oxidative phosphorylation stoping insect, also has ovicidal, presses down food, oviposition deterrence and bactericidal action.
Allicin (Allicin) is a kind of organosulfur compound extracted from the bulb (garlic) of Liliaceae allium garlic (Allium Sativum), is also present in onion and other alliums.Formal name used at school GIUCOSinoate.Pale yellow oily liquid body.Boiling point 80-85 DEG C (0.2kPa), relative density 1.112(20/4 DEG C), index of refraction 1.561.Be dissolved in ethanol, chloroform or ether.Solvability 2.5% (quality) (10 DEG C) in water, its pH value of water solution is 6.5, has grease sediment to be formed time standing.With ethanol, ether and benzene can dissolve each other.Unstable to thermokalite, acid is stablized.By being present in the bulb of liliaceous plant garlic, under large allinase effect, transform generation by the garlic aminoacid existed.Also be present in the bulb of green onion.Have strong large garlic odour, taste is peppery.
In the real process of agricultural production, the problem that pest control the most easily produces is the generation of pest resistance to insecticide.Different cultivars composition carries out composite, is to prevent and treat the very common method of resistant insect.Heterogeneity is carried out composite, according to practical application effect judge certain composite be synergy, add and or antagonism.
Summary of the invention
For the problems referred to above, the invention provides one and to grow cotton insecticide, the present invention is a kind of microemulsion for preventing and treating cotton cotton bollworm, and its active ingredient is Tolfenpyrad and allicin, and instant effect of the present invention, holding effect are long, to non-target crop safety.
