Abstract
The invention discloses a long-persistance pesticide which is characterized by comprising the following raw material components in parts by weight: 10-15 parts of a mixed agentia, 2-4 parts of a norflurazon raw drug, 3-5 parts of a carrier fertilizer, 2-2.2 parts of borax, 1-2 parts of ethyl cellulose, 3-5 parts of a packing, 0.5-0.7 part of cetyl trimethyl ammonium bromide, 5-7 parts of a chitosan solution, 0.3-0.5 part of sodium tripolyphosphate, 2-3 parts of polyvinyl alcohol, and 0.8-1 part of Arabic gum. The mixed agentia and the norflurazon raw drug keep the original rapid killing characteristic of all pesticides; after the packing and chitosan are added, the embedding and adsorption of the pesticide are effectively combined, and the pesticide release time is significantly prolonged; with compounding of the carrier fertilizer, a right amount of needed nutrient elements are provided for plant planting while insects are killed, and the pesticide has wide insecticidal spectrum and has the persistance.
Description
Technical field
The invention belongs to technical field of pesticide preparations, be specifically related to a kind of long long-lasting agricultural chemical insecticide.
Background technology
Along with the continuous progress of cultivation technique, the vegetative period of vegetables is shorter and shorter, and along with the aggravation of environmental pollution, the disease and pest of vegetables is also more and more heavier, and most vegetables could ripe listing after needing continuous several times to put medicine.What pesticidal contamination was heavier has leafy vegetable, and wherein the pollution ratio that is subject to of leek, rape is maximum.Solanaceous vegetables is as green pepper, tomato etc., and tender pod class vegetables are as fresh kidney beans etc., and bulb vegetable is as green onion, garlic, onion etc., and the pollution of agricultural chemicals is relatively little.At present, China's pesticide species is still based on general formulations such as missible oil, after being administered to plant or soil, major part activeconstituents is with the loss of surface runoff or with soil moisture vertical movement leaching loss, enter earth's surface or groundwater regime, reduce agricultural chemicals utilising efficiency on the one hand, bring serious problem of environmental pollution on the other hand.Employing slow release method can according to prevention target requirement, the release rate of reasonable adjusting pesticide activity component, thus improves drug effect, prolongation lasting period.The core of control release technic is that macromolecular compound and agricultural chemicals interact, pesticide activity component can according to the concentration preset and time (according to the prevention and control of plant diseases, pest control need formulate) continue and be discharged into lentamente in environment, and a specific concentration can be maintained for a long time.Therefore, the slow release formulation of agricultural chemicals can make powder performance more stable due to the provide protection of polymer substance, decreases the impact of the environmental factor such as water, air; Secondly, slow release method can extend the lasting period of same dose agricultural chemicals greatly, thus can reduce the access times of agricultural chemicals and total consumption, and possibility that is residual and environmental pollution is significantly reduced; Again, slow release method can reduce toxicity and the poisoning of agricultural chemicals.Therefore pesticide slow-release technology is subject to extensive concern.
Chlorfenapyr is broad spectrum insecticide, miticide; Have stomach toxicity and action of contace poison concurrently; With other sterilants without cross resistance; Crop has medium residual activity; Through the selective systemic activity of Root Absorption in nutritive medium; Medium to Mammals Oral toxicity, percutaneous toxicity is lower.
Cartap under normal operation to eyes and skin without anaphylaxis.Have no carcinogenic, teratogenesis, mutagenesis.Poisonous to fish, to honeybee and silkworm poisonous, to birds low toxicity, nontoxic to natural enemies such as spiders.
Along with pesticide species is to high reactivity, low dosage development, agricultural chemicals significantly declines at the unit surface application dosage in field, the agricultural chemicals all fully solving preparation of the sustained-release pesticides of preparation both kept the quick-acting of original medicine, it is long-lasting to turn increase, the problem that insecticidal spectrum is wide.
Summary of the invention
The object of the present invention is to provide a kind of long long-lasting agricultural chemical insecticide, maintain the original speed of each sterilant and kill characteristic, farm chemical release time significant prolongation; Again for kind of plant provides appropriate required nutritive element while desinsection, it is wide and have long-lasting that this agricultural chemicals has insecticidal spectrum.
The technical scheme that the present invention takes is:
A kind of long long-lasting agricultural chemical insecticide, it is characterized in that, feed components is composed as follows according to weight fraction:
Confection 10-15 part, norflurazon former medicine 2-4 part, carrier fertilizer 3-5 part, borax 2-2.2 part, ethyl cellulose 1-2 part, filler 3-5 part, cetyl trimethylammonium bromide 0.5-0.7 part, chitosan solution 5-7 part, tripoly phosphate sodium STPP 0.3-0.5 part, polyvinyl alcohol 2-3 part, gum arabic 0.8-1 part.
Described confection is the mixture that the cartap of 85-90% and Chlorfenapyr form according to weight ratio 2:1.
Described filler is the mixture that white kaolin, attapulgite and W-Gum form according to weight ratio 2:2:1.
The mixture that described carrier fertilizer is ammonium chloride, urea, potassium sulfate form according to weight ratio 1:3:2.
Described chitosan solution is that in the ethanol being dissolved in pH=2-3, mass content is the chitosan solution of 1-1.2%.
Beneficial effect of the present invention is:
The combination of confection in the present invention, norflurazon former medicine maintains the original speed of each sterilant and kills characteristic, after filler and chitosan being added, the embedding of agricultural chemicals and adsorption is effectively combined, farm chemical release time significant prolongation; Composite with carrier fertilizer, again for kind of plant provides appropriate required nutritive element while desinsection, it is wide and have long-lasting that this agricultural chemicals has insecticidal spectrum.
