Description
Technical field
The present invention relates to a kind of agricultural chemical composition for disinsection, specifically relate to a kind of compound pesticide composition that contains indoxacarb.
Background technology
In recent years, due to single drug and Scientific Usage of Drugs not, cause many insects to produce pesticide resistance to the agricultural chemicals of current use, as diamond-back moth, cotton bollworm etc., become a great problem of disease worm chemical control.
Indoxacarb is a kind of novel oxadiazines insecticides, and its insecticidal mechanism is by the sodium-ion channel in blocking-up insect nerve cell, makes the nerve cell loss of function of insect and is benumbed, and the coordination ability declines, finally dead.Medicament works by contacting or take food to enter in polypide, does not have cross resistance with other insecticide.To agriculture and garden crop pests such as vegetables, beet, cotton, fruit tree, tea tree, potato, gardening, flowers, as high in lepidoptera pest activity such as beet armyworm, tomato moth, imported cabbageworm, cotton bollworms, and each instar larvae is had to good control efficiency.Meanwhile, very safe to natural enemy insect, low-residual in crop, is the desirable medicament that can be used for control of insect in Agricultural product without pollution.But indoxacarb is partially short to the lasting period of control of insect, so single use has certain limitation.
Bacillus thuringiensis,Bt (Bacillus thuringiensis is called for short Bt) is current production rate maximum, the widest biological insecticides of use.Its main active is one or several insecticidal crystal proteins (insecticidal crystal proteins, ICPs), claim again delta-endotoxin, to Lepidoptera, coleoptera, diptera, Hymenoptera, the insects such as Homoptera, and animals and plants nematode, the arthropodss such as acarian have specific cytotoxicity, and to nontarget organism safety, therefore, Bt insecticide has single-minded, efficient and to advantages such as person poultry safeties, bacillus thuringiensis,Bt commodity preparation has reached kind more than 100 at present, to be most widely used in the world, consumption maximum, the microorganism insecticide that effect is best, thereby extremely people pay close attention to.But, commodity Bt preparation also demonstrates some limitation producing in control, and unstable etc. all having become of short and recombinant strain genetic character of phase imitated in as poor in quick-acting, insensitive on high instar larvae, field late affect the further restraining factors of successfully promoting the use of of Bt.Therefore,, in order to improve the insecticidal effect of Bt preparation, to the research of its synergy approach study hotspot that become international, mainly comprise: screening synergy bacterial strain; Utilize chemical addition agent, plant allelochemics, chitinase as synergistic matter; Between entomopathogen, do mutually synergy etc.
Jervine is that various Veratrums produce a kind of poisonous alkaloid.Can be used as insecticide, its mechanism of action is jervine through polypide surface or sucks and enter digestive system, causes local excitation, causes the excitement of reflectivity polypide, then suppresses polypide sensory nerve ending, through conduction with suppress nervous centralis and cause insect death.This product active ingredient is alkaloid, and after using, degraded gradually, can not produce enrichment phenomenon, can not pollute environment, does not injure Natural Enemies of Insects, can effectively preserve the ecological environment, and reaches the object of integrated control.This product platymiscium source pesticide made of Chinese medicinal herbs, active ingredient is diversity, and to sick worm mechanism of action relative complex, compared with the chemical synthetic pesticide single with active ingredient, sick worm is difficult to develop immunity to drugs to it.This product lasting period is longer than chemical pesticide, can reach 7-14 days, saving of work and time, and utilization benefit is higher.And do not produce poisoning, to features such as crop safeties.
Thiodicarb belongs to benzoyl area kind Chitin synthesis inhibitor, is insect hormone.By suppressing the activity of insect cuticle chitin synthetase and urine nucleosides coenzyme, thereby suppress that insect chitin is synthetic causes insect normally not cast off a skin and dead.Use in the unhatched ovum stage, thiodicarb can affect DNA and the proteometabolism in respiratory metabolism and the embryo development procedure of ovum, makes larva in ovum lack chitin and death immediately after can not hatching or hatch; Use in larval phase, thiodicarb can make the new epidermis of insect form to be obstructed, and delayed development, or lack hardness can not normally be casted off a skin and caused death or form lopsided pupa death.To abnormal insect, particularly lepidopterous larvae thiodicarb also shows good insecticidal activity.
Phenthoate dimephenthoate cidial has to insect the inhibitory action of growing significantly, and trialeurodes vaporariorum is had to special efficacy, and the 2-announcing than world patent document WO9533711 is bromo-3, and the activity of two (trifluoromethyl) phenyl benzoylureas of 5-is high 25～50 times.This compound suppresses insect chitin and forms, affect endepidermis and generate, insect can not be casted off a skin smoothly and death, can effectively prevent and treat most of lepidoptera pests of the various plants such as vegetables, tealeaves, cotton, antagonism insect is generally effective, and to crop, natural enemy, people and animals and environment high safety.
Decis is safety, efficient, low toxicity broad spectrum activity organosulfur acaricide, has stronger tagging and stomach poison function, is one of large-tonnage miticide kind in the world, uses so far for three more than ten years abroad, still without obvious pesticide resistance problem.Can be widely used in the harmful mite of control cotton, citrus, apple, vegetables, tea, flowers and other crops, if it is all excellent to kill into mite mite, young mite and mite ovum effect, also can kill the harmful mite that other insecticides is had to resistance.Can prevent and treat the evil mites such as citrus red mite, European red mite, cotton vegetables two spotted spider mite, tealeaves goitre mite, pink tea rust mite.
On agricultural insect pests control, often there is defect in various degree in the insecticide that contains a kind of active component.For example, use continuously a kind of insecticide easily to cause developing immunity to drugs; Meanwhile, frequent dispenser causes again peasant burden to increase the weight of and increasing environmental pollution.Therefore, be badly in need of at present the insecticide new varieties of efficient, minuent, environmental protection, low-residual.
