Technical field
The present invention relates to a kind of injection drying agent and nimbin that contains nimbin and in fruit tree, gardens and forestry, adopt the application of annotating the drying method prevention and elimination of disease and pests.Belong to pesticide field.
Background technology
Nimbin is from the Meliaceae plant, for example print extract in the chinaberry (Azadirachtin indica) efficient, low toxicity, low-residual, the natural agricultural chemicals of environment-friendly type nontoxic to the person poultry safety, non-environmental-pollution, be one of current biopesticide of praising highly the most, can be widely used in damage by disease and insect such as control pest, evil mite and nematode.Its mode of action mainly is, food refusal/repellent action, breed inhibitory action, the repellent action of laying eggs, insect growth regulating action etc., have advantages such as being difficult for developing immunity to drugs, not injuring natural enemy and other non-target organism.Its shortcoming is unstable, studies show that other active ingredient in nimbin and the seal chinaberry decompose under the situation that strong sunshine, high temperature and organic solvent exist easily; They are two years old; plant insecticide must be relatively stable lasting as its food refusal of anti-feedant; if keep the food refusal effect in longer stage; anti-feedant should be in the various piece conduction of plant; the new first portion of plant is lacked a big shortcoming of absorption anti-feedant in the protective effect right and wrong, and these new lives and the position that does not contact anti-feedant may be subjected to the harm of insect.Have report to confirm that nimbin and other seal chinaberry preparations have interior absorption when executing in soil and water, still, nimbin it be unclear that by the conduction of foliage-spray in plant.
Nimbin belongs to four and falls triterpene compound, and the ISO adopted name is Azadirachtin, molecular formula C
35H
44O
16, the CIPAC digital code is 11141-17-6, chemical structural formula:
At present, it mainly is by modes such as surface spray, filling roots that nimbin uses as agricultural chemicals, because factors such as high temperature, ultraviolet ray can be quickened the degraded of active ingredient, influences the Expected Results of medicament by the surface spray mode; Can be by the mode of irritating root because soil absorbs and infiltration reduces the absorption efficiency of plant to agricultural chemicals.
Summary of the invention
In order to solve the problem of above-mentioned existence, the purpose of this invention is to provide a kind of injection drying agent that contains nimbin, and the mode by directly injecting, make nimbin directly enter plant tissue inside, reduce the influence of environmental factor to nimbin.
Technical scheme of the present invention is achieved in that a kind of injection drying agent that contains nimbin, is made up of the female medicine (being neem extract) of nimbin, cosolvent, bleeding agent, composite dose and thinner, and its composition proportioning is as follows:
The female medicine of nimbin: for containing the neem extract that nimbin is 1%-60% by weight;
Cosolvent: the amount that adds cosolvent in the female medicine of every gram nimbin is the 1-30 milliliter;
Thinner: be the buffer solution of pH4-7, female medicine of nimbin and cosolvent are diluted to the dilute solution that contains the female medicine 0.001%-30% of nimbin by weight;
Bleeding agent (adding as required): the 0%-1% by female medicine of nimbin and cosolvent dilution back cumulative volume adds.
Composite dose (option):, add 1-2 kind chemical pesticide or other biological agricultural chemicals as auxiliary element according to the needs of controlling object and index for control.
Described cosolvent can be ethanol, acetone or other neutral organic solvents.
Described bleeding agent is the solvent that azone or other have anatonosis (penetrating) effect.
The female medicine of nimbin be from seal chinaberry seed or its hetero-organization through extraction, purify, concentrate the dry powder shape material that forms, can use after must being processed into preparation, directly the female medicine of nimbin is sprayed or annotates that to do technical operability not strong; And on the other hand, the female medicine of nimbin is more stable under normal environmental condition, therefore, adopt that " cocktail method " is now with the current can significantly save the preparation cost and can extend the expiration date, the concrete grammar of its preparation is: the female medicinal cosolvent of nimbin is fully dissolved, add bleeding agent, composite dose as required, do use with thinner dilution back for annotating again, the medicament for preparing is preferably within 24 hours and uses up, in order to avoid the active ingredient degraded.Can be directly used in the nimbin preparation of annotate doing if directly be processed into, then need in process, also need add protectants such as anti-photodissociation agent, stabilizing agent, make behind the preparation because of the degraded in the long term storage process to reduce nimbin as far as possible.
Another object of the present invention provides nimbin annotating dried Application for Field, and nimbin directly is injected in the trunk.
Nimbin is made the injection drying agent that contains nimbin, injection drying agent directly is injected in the trunk
Inject the position and be generally, inject the degree of depth and reach xylem apart from the trunk more than the 10cm of ground.
Compared with prior art, the invention has the beneficial effects as follows:
1, the method by directly injecting can effectively reduce the loss of other application methods (as modes such as surface spray, filling roots) to agricultural chemicals, and to the pollution of environment.
2, the mode that adopts notes to do is directly injected nimbin in the plant corpus, can effectively avoid main active ingredient nimbin to degrade fast because of factor effects such as ultraviolet ray, high temperature.
3, the nimbin that enters in the plant tissue can be well absorbed conduction, can keep the biologically active of long period in plant corpus, thereby protect target plant long-term effectively.
4, because the nimbin mode of action mainly is by food refusal/repellent, and influence reproduction etc., therefore, in the short term, toxic action to insect is not obvious, but can long-term effectively pest population be controlled at reduced levels, and can not impact natural enemy.
