Abstract
The present invention discloses a kind of tea place insecticide, wait the tea fruit processed fully to mix with ten weight portion alcohol and be heated to 50-55 DEG C through shelling a weight portion to soak 2 hours, wherein within every 30 minutes, stir once, filter after soaking, get filtrate in spin concentration instrument, reenter equal volume amounts pure water, below the half being concentrated into original volume under the vacuum of 0.08Mpa, then to add concentration be 2% chitosan solution 1/10 parts by volume; Refilter, getting in filtrate to spin concentration instrument and being concentrated into concentration is about 2%.Advantage of the present invention: the production material source of this insecticide is extensively easy to get, and cost of equipment is low, simple to operate, and extraction efficiency is high, harmless to human non-toxic.More crucially this insecticide both directly can use as tea place part insect (tea aphid, smaller green leaf hopper) agent for killing, can use as the synergist of other agricultural chemicals of tea place again, coordinate other Pesticide use, greatly can improve the adhesion effect of agricultural chemicals and spray evenness.
Description
Technical field
The present invention relates to a kind of tea place insecticide, especially a kind of tea aphid, tea lesser leafhopper insecticide.
Background technology
Tealeaves as the fashionable whole world of a kind of healthy beverage, tea tree in the course of cultivation, the use of chemical pesticide, effectively control the growth of tea place damage by disease and insect, substantially increase the yield and quality of tealeaves, the Pesticide Residue simultaneously also brought, brings hidden danger to tealeaves safe for drinking.Cause the attention of people.And in tealeaves international trade, Pesticide Residue has been no longer simple food-safety problem, becomes developed country and implemented the manageable important means of trade.
For successfully managing and addressing this problem, the tea place extermination of disease and insect pest is except setting up effective green prevention and control system, select efficient, low toxicity (or nontoxic), safety chemical pesticide substitute, also be a kind of effective measures, in this case, biopesticide, botanical pesticide are widely using gradually in tea place.This agricultural chemicals easily in the environment with fast decoupled in organism, can not environmental pollution be caused.The Main way of Development in Green Pesticides from now on will be become.
Tea aphid and tea lesser leafhopper are all the tea place primary pests that harm tea tree mainly utilizes position-tender shoots leaf.These two kinds of insects are all that polypide is less, and have the characteristic that thorn inhales juice, through harm leaf not only growth arrest, affect output, and have a strong impact on the quality of tea products, especially larger to the Influence of production of Famous High-quality Tea.The product of patent of the present invention has good preventive effect to these two kinds of worms in tea place, and has certain selectivity, has no significant effect natural enemy.
Summary of the invention
The object of the present invention is to provide a kind of tea plant pest insecticide, the production material source of this insecticide is extensively easy to get, and cost of equipment is low, simple to operate, and extraction efficiency is high, harmless to human non-toxic.More crucially this insecticide both directly can use as tea place part insect (tea aphid, smaller green leaf hopper) agent for killing, can use as the synergist of other agricultural chemicals of tea place again, coordinate other Pesticide use, greatly can improve the adhesion effect of agricultural chemicals and spray evenness.
Technical scheme of the present invention is: a kind of tea place insecticide, wait the tea fruit processed fully to mix with ten weight portion alcohol and be heated to 50-55 DEG C through shelling a weight portion to soak 2 hours, wherein within every 30 minutes, stir once, filter after soaking, get filtrate in spin concentration instrument, reenter equal volume amounts pure water, below the half being concentrated into original volume under the vacuum of 0.08Mpa, then to add concentration be 2% chitosan solution 1/10 parts by volume; Refilter, getting in filtrate to spin concentration instrument and being concentrated into concentration is about 10%.
Advantage of the present invention: the production material source of this insecticide is extensively easy to get, and cost of equipment is low, simple to operate, and extraction efficiency is high, harmless to human non-toxic.And this insecticide both directly can use as tea place part insect (tea aphid, smaller green leaf hopper) agent for killing, can use again, coordinate other Pesticide use as the synergist of other agricultural chemicals of tea place, greatly can improve the adhesion effect of agricultural chemicals and spray evenness.
concrete occupation mode
A kind of tea place insecticide, concrete technology comprises (1) Feedstock treating: tea tree ripening fruits removes pericarp, seed hulls etc., and to dry (drying) to moisture be about 10%, pulverizes stand-by through cracker.(2) lixiviate: a raw material ﹢ ten parts of alcohol fully mix, 50-55 DEG C is soaked 2 hours, wherein within every 30 minutes, stirs once; (3) turn molten: after lixiviate through leaching filtrate in spin concentration instrument, and add the pure water of equivalent, under 0.08Mpa vacuum, about being concentrated into the half of original volume, (or to be advisable when thickening temperature rises to 55 DEG C.(4) flocculate: in concentrate, add the chitosan solution (addition is 10% of concentrate volume) of 2%.Supernatant is got after centrifugal.(5) concentrated: it is about 10% that the supernatant got in (4) is concentrated into concentration again, is a kind of novel tea place pests insecticide.
The insecticide obtained through above-mentioned steps can be used for killing tea plant pest tea aphid, smaller green leaf hopper etc., concrete using method is: above-mentioned insecticide dilutes 100 times, with manual sprayer in without even spraying during dew in leaf of being injured, note when spraying spraying tow sides, when insect pest situation is serious, relevant agricultural chemicals can be coordinated to use as pesticide synergistic agent, and effect more.
