Abstract
A chemical for effectively preventing and eliminating pests and mouldfungus of grains is prepared from boride, calcium chloride and powdered tangerine peel through mixing and grinding. It is used by mixing with grains (rice, corn, wheat, etc.).
Description
The present invention relates to a kind of mould agent for prevention and treatment of injurious insects in grain, particularly the mould microbial inoculum of chronic pest control of paddy, wheat, corn.
As everyone knows, paddy, wheat and corn are topmost grain on the our times, and these grains take place when storing by insect pest and mould easily, and the grain quantity of annual loss is very big.At present, the way of modal control worm, control mould is to adopt toxic agent to fumigate or control methods such as temperature, humidity, anoxic management, though obtain some effects, but can not eradicate, also require grain depot to seal simultaneously, investment is expensive, non-general grain depot can be born, main is that the grain of fumigating contains a certain amount of poisonous substance, and healthy influential to the people sought a kind of simple and feasible, the nontoxic mould microbial inoculum of pest control is current scientist's a task.
The object of the present invention is to provide effective, the avirulence of a kind of pest control mould, the mould agent for prevention and treatment of injurious insects in grain that general grain depot all is easy to use.The water-soluble height of this agent is removed clean after washing easily before eating.It is the mould agent for prevention and treatment of injurious insects in grain of a new generation.
Embodiment of the present invention are as follows:
(1) prescription (following) all in weight portion:
Acidifying calcium chloride: 40～55
Boride (as boric acid or borax or boron oxide): 30～50
Dried orange peel powder: 10～15
(2) preparation method: above-mentioned three components are ground to form 0.5 micron to 10 micron grain sizes in universal grinding machine, mix then and form.
(3) mechanism is tentatively inquired into:
(a) acidifying calcium chloride is a kind of absorptive chemicals that has, and has acidity (it is the salt that is formed by strong acid weak base) after the suction, and the pH value of the general aqueous solution is about 4-5.And the insect pest of grain, proved that as lesser grain borers such as corn and various mould the pH value of surrounding environment just can not survive about 4, the adding of calcium chloride like this, one side reduces the moisture content of grain, make insect pest be difficult for existence, and the main PH that causes grain environment on every side just can play the effect of pest control mould effectively about 4.
(b) boric acid or borax or boron oxide, these borides are traditional detoxifcation preservatives.Special the disclosing among the clear 64-34905 of Japan Patent is insect-proof agent as timber.Do not relate to and be applied to grain.Though report is used for grain and does the Vermins-proof mildew-proof agent in CN1065972A, its effect is not good yet, and main cause is mismatched calcium chloride and is difficult to reach the PH of grain surrounding environment about 4.Only by insect pest and the extremely strong various moulds of intractable such as the anticorrosion difficult removing corn weevil lesser grain borers of the gas defence of boride.
(c) dried orange peel powder.Be a kind of Chinese medicine, be used on the traditional Chinese medical science to help digestion, the common Chinese medicine of promoting the circulation of qi.Contain various acids, its infusion also has acidity, so also can play the Vermins-proof mildew-proof effect.
More than the combination of three kinds of components, under synergy, helping causing around composition PH is about 4 environment, so even mixed distribution mould proof effect of pest control effectively just in grain.
This agent is to belong to chronic pest control mould, is suitable for the grain memory period, rather than pest control agent fast, and general quick insecticide is bigger to the toxicity of human body.
Following preference is described in detail the present invention, but does not mean that limitation of the scope of the invention:
Preparation example 1: the preparation of acidifying calcium chloride is with 5 kilograms of 100 kilograms of usefulness of commercially available calcium chloride, 1% hydrochloric acid washing 2 times, and control is done, in 60 ± 5 ℃ down oven dry form (these acidifying calcium chloride 4 grams be dissolved in record solution ph in 100 ml waters be 4).
