Description
Technical Field
The invention belongs to the technical field of sterilization and deinsectization, and particularly relates to a pesticide for sterilizing and disinsectizing vegetables and fruits.
Background
In order to achieve the effects of sterilization and deinsectization in the planting process of fruits and vegetables, a large amount of pesticides are used in the cultivation process, for example, in the cultivation process of tremella, penicillium, trichoderma, chitinase (commonly called powdery mildew), rhodotorula and the like are mainly harmful to sporocarp, the most common and serious harm is caused to the chitinase, and the diseased lugs form a layer of powder and the tremella sporocarp is hardened. The fruiting body with serious disease should be removed in time, and then controlled by spraying lime sulfur mixture.
For another example, common pests in the process of cultivating tremella include nematodes, mites, fungus flies, slugs and the like, wherein the nematodes are main pests causing ear rot, and the fungi cannot be nourished and rot due to the fact that fungus bases are invaded. The pesticide can be used for preventing and controlling 0.1-0.2% dipterex sprayed on the auricularia auricula-judae, and can inhibit the propagation of nematodes. Mites are also the main pests of tremella, reproduce very quickly, often eat hypha and ear roots, after the occurrence, 0.5% of dichlorvos is applied to spray an earfield and 1: 800 times of 20% wettable acaricide sulfone can be used for soaking the agaric wood (immediately taken out after soaking) or spraying the agaric wood for control, and 800 times of dimethoate or dipterex can also be used for spraying and killing.
The use of a large amount of pesticide can ensure the yield of fruits and vegetables, but also cause pesticide residues on the fruits and vegetables, thereby affecting the quality of the fruits and vegetables.

Detailed Description
The present invention will be further described with reference to the following examples, which are intended to illustrate only some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
A pesticide for sterilizing and killing insects on vegetables and fruits comprises pesticide and acidic electrolyzed water.
The acid electrolyzed water is an acid stock solution with the pH value of 1.5-2.0 and generated by using sodium chloride as electrolyte through electrolysis, the oxidation-reduction potential ORP of the acid stock solution is 900 mv-1200 mv, the mass fraction of sodium in the acid stock solution is less than or equal to 0.01%, and the concentration of chlorine in the acid stock solution is 80-150 mg/L.
The ORP value of the acidic electrolyzed water is 900 mv-1200 mv, and the ORP value of the acidic electrolyzed water can be selected from 900mv, 1000mv, 1100mv, 1150mv, 1185mv and 1200mv during the specific production and use process. The ORP value of the preferable acidic electrolyzed water is 1185-1200 mv, and in the range, the ORP value is better for sterilizing and killing insects, and meanwhile, the growth of plants can be promoted.
The effective chlorine concentration of the acidic electrolyzed water can reach 80-150 mg/L, for example, the effective chlorine concentration is 80, 90, 95, 100, 110, 115, 121, 130, 133, 140, 145 and 150 mg/L. Preferably, in order to improve the sterilization and disinsection effects, the effective chlorine concentration is 100-150 mg/L.
The pH value, the oxidation-reduction potential and the effective chlorine concentration of the acidic electrolyzed water are different from those of the acidic electrolyzed water in the prior art, and the acidic electrolyzed water in the prior art cannot reach the physicochemical indexes of the pH value, the ORP value and the effective chlorine concentration of the acidic electrolyzed water in the invention; therefore, the invention has better sterilization and deinsectization effects in the using process.
The volume ratio of the acidic electrolyzed water to the pesticide is 1: 0.1-0.3. In the process of mixing the acidic electrolyzed water and the pesticide, the proportion of the acidic electrolyzed water and the pesticide can be properly adjusted according to the occurrence condition of the pest, so as to achieve the best effect, for example, when the pest is serious, the dosage of the pesticide can be properly increased, and when the pest is light, the dosage of the pesticide can be properly reduced, which is clear and obvious for a person skilled in the art, and is not described herein again.
The pesticide is chlorothalonil, chlorpyrifos, trichlorphon, carbendazim, dichlorvos or dimethoate and other common pesticides.
The following tests were carried out on common fruits and vegetables as follows

According to the table, the acidic electrolyzed water and the pesticide are mixed to thoroughly kill infectious mixed bacteria and pests in the vegetable cultivation process, so that the normal growth of the tremella can be guaranteed.
Example two
As can be seen from the above table, the acidic electrolyzed water of the present invention can be widely applied to the prevention and treatment of insect pests of fruit trees.
The following comparative tests were carried out using pakchoi
The comparison shows that the pesticide residue can be greatly reduced when the acidic electrolyzed water is added into the pesticide and then the pesticide is used for sterilization and disinsection operation of vegetables and fruits.
In the above comparative test, the detection apparatus mainly includes a gas chromatograph, and the detection limit of the method is 0.0003.
In conclusion, after the acidic electrolyzed water is mixed with the pesticide, the effects of sterilizing and killing insects can be achieved, the using amount of the pesticide can be reduced, pesticide residues are greatly reduced, and the quality of fruits and vegetables is improved.
