The embodiment of the utility model provides a synergist its insecticidal effect, its insecticidal principle as follows: after the synergist is sprayed on the body surface of pests, some sulfides are reduced into solid flow, and the solid sulfur and micro particles in the solution block the air valves of the insects, so that the insects can not breathe and die by suffocation; the synergist can also perform a series of chemical reactions with oxygen and moisture in the air, and can release a small amount of hydrogen sulfide gas which is toxic and can kill pests; meanwhile, the effective components in the synergist can decompose and soften the wax layer and the body wall of the scale insects or the mite eggs, and permeate into the insect body, so that the scale insects or the mite eggs die due to poisoning, and the synergist also has a certain sterilization effect.
The embodiment of the utility model provides a when synergist adds the plasma aquatic of disinfecting: after the mixed liquid of natural pesticide and plasma sterilizing water is sprayed onto the surface of pests, the hypochlorous acid in the plasma sterilizing water can act on cell wall and virus shell in the course of sterilizing and killing pests, and the hypochlorous acid can produce molecular reactionTo generate oxidation reaction to kill pathogenic microorganism, i.e. R-NH-R + HC L O → R2NCL+H2O; meanwhile, the chlorine ions generated by hypochlorous acid can also obviously change the osmotic pressure of cells and virosomes, so that the cells and the virosomes lose activity and die. When the plasma sterilizing water and the natural insecticide are mixed, the insecticidal effect of the natural insecticide is further enhanced; the scale inhibitor enhances the oxidative decomposition capability of the wax layer and the body wall of the scale insect or the mite egg, and has faster and stronger penetration to the interior of the insect body, thereby achieving more efficient and wider spectrum of sterilization and disinsection. Has good control effect on pests such as leaf mites, rust mites, scale insects, red spiders, green insects and the like, and diseases such as powdery mildew, rot disease, scab, resina diseases and the like.
The plasma sterilization water has acid-base property: weakly alkaline plasma sterilizing water, which contains 0.2 to 2 percent of saline water, has the concentration of hypochlorous acid of 20 to 200ppm and the pH value of more than 7.5; weakly acidic plasma sterilizing water containing 2 to 6% hydrochloric acid, wherein the concentration of sodium hypochlorite is 10 to 30ppm, and the pH value is 5 to 6.5.
The sterilizing capacity of the plasma sterilizing water is different along with the difference of the acid-base properties of the solution. Generally, acidic solutions have a higher bactericidal capacity than alkaline solutions. Particularly, in the aspect of controlling spores, the acidic solution has higher bactericidal activity than the alkaline solution. In contrast, an alkaline solution has higher bactericidal activity than an acidic solution in terms of bactericidal activity against mold. It is therefore preferred to adjust the properties of the solution to be acidic or basic depending on the fungus to be killed, thereby providing it with a better bactericidal activity. However, it is known that if the acidity is too strong, hypochlorous acid decomposes to generate chlorine gas, and as a result, the oxidizing ability of the hypochlorous acid sterilizing ability is lowered. In order to maintain the bactericidal activity, the solution is preferably adjusted to a pH of 3 to 7 at 20 ℃. The concentration of the salt added in advance in the acid-base state can be adjusted. Or adding hydrochloric acid or water-soluble organic acid such as succinic acid, lactic acid, citric acid, acetic acid, etc. to adjust acidity; sodium hydroxide, sodium carbonate, sodium bicarbonate, etc. are added to make the mixture alkaline.
The working principle of the plasma generator is as follows: when the low-voltage direct current is used for ionizing tap water, the reaction on the positive plate is as follows:
2H2O＝O2+4H++4e (1)；
3H2O＝O3+6H++4e (2)；
oxygen and ozone are generated by the reaction of (1) and (2).
When chloride ions are present in tap water:
CL-+H2O＝CLO-+2H++2e (3)；
H++CLO-＝HCLO (4)；
hypochlorous acid is generated by the reaction of (3) and (4).
When the brine is ionized by low voltage direct current, the reaction on the positive plate is carried out, besides the reactions (1), (2), (3) and (4), the following reactions are carried out:
Na++CLO-＝NaCLO；
according to chemical measurement, the sodium hypochlorite with ppm level concentration is almost completely hydrolyzed into hypochlorous acid in water, namely NaC L O + H2The ozone and hypochlorous acid generated by the method have strong sterilizing capability, and the salt water is ionized by a plasma generator to generate much more hypochlorous acid than ozone.
