A kind of natural organic agricultural chemical composition and preparation method thereof
Technical field
The invention belongs to pesticide production technology field, be specifically related to a kind of natural organic agricultural chemical composition and preparation method thereof.
Background technology
In agricultural production, insect can disturb the growth of crops, both have impact on the yield of crops, and had also caused food safety tired
Disturb.Therefore, most peasants can select chemical pesticide to carry out pest control.But in recent years, owing to abusing what chemical pesticide caused
Problem is increasingly subject to pay attention to.First, abuse chemical pesticide can make the Drug resistance of insect increase, it is reported that, conventional pesticide has
Effectiveness amount 10 years is general rises three times, so on, insect pasts medical help and not paints an alarming picture of the situation just to scare the audience.Secondly, although the using of chemical pesticide
Improve the yield of crops, but difficulty dispelled by the chemical pesticide of residual, healthy to people causes the biggest threat.Finally,
After unnecessary chemical pesticide flows into river, meeting severe contamination water quality, not only can not drink, also can form algae and spread unchecked, ecological mistake
The disastrous effect of weighing apparatus.Therefore, Novel high-efficient pesticide is sought extremely urgent.
Natural organic agricultural chemicals is the natural pesticide being transformed by agricultural products, both can make full use of the agricultural resource of plantation, the most not
Can impact health and the environment of human body, putting forth effort to develop natural organic agricultural chemicals is a main trend.
Summary of the invention
Based on foregoing, the present invention uses various plants source extract combination to form natural organic agricultural chemicals, has the pest-resistant of wide spectrum
Effect, can be widely applied to the pest control of veterinary antibiotics, Chinese crude drug, has the chemistry such as notable, the green safety of insecticidal effect
The effect that pesticide is not replaced.

Experimental example
The pesticide stock solution that embodiment 1~20 is prepared dilute with water 1000 times respectively, 1500 times, 2000 times, and test variant
Concentration pesticide, to scale insect, spider mite, sugar moth, heart-eating worm, leaf folder, Pieris rapae, the suppression ratio of wood louse, is shown in Table 1.
Suppression ratio (%) to various insects after the pesticide dilution that table 1 embodiment 1~20 prepares
As can be seen from Table 1, the natural pesticide compositions of the present invention has an insecticidal effect of wide spectrum, wherein for scale insect, six
The suppression ratio of some yellow spider and sugar moth is the highest, and the insect suppression ratio in embodiment 17 is the highest, is the optimal choice of inventive formulation.
Additionally, same pesticide stock solution extension rate is the lowest, insecticidal effect is the strongest.
