Currently, all kinds of the disadvantages brought about by the long-term use of traditional chemical pesticides have been appeared: Excessive pesticide residues in the agricultural products, increase of human and livestock poisoning incidents, pesticide resistance of pests, sharply decrease of natural enemy pests, disruption of ecological balance, etc. Therefore, many pesticides with high toxicity, residue and persistence have been prohibited to be used.
Since January 1st, 2007, 5 kinds of high toxic organophosphorus pesticides, including methamidophos, parathion, parathion-methyl, monocrotophos and phosphamidon, have been prohibited to be used in the agricultural industry. How to select the substitutes after these pesticides are prohibited to be used? The botanical pesticides (previously called “native pesticides”) in the biological pesticides are thought highly of now.
Currently, the varieties that have obtained the three pesticide certificates include 0.1％ rhodojaponin-Ⅲ emulsifiable concentrate, 0.3％ and 0.5％ azadirachtin pesticide emulsifiable concentrates, 2.5％ rotenone emulsifiable concentrate, 3.5％ hypertonic rotenone emulsifiable concentrate, 0.20％, 0.36％ and 0.60％ matrine aqueous solution, 0.23％ matrine emulsifiable concentrate, 1.1％ matrine powder, 10％ nicotine emulsifiable concentrate, 27％ nicotine oleata emulsifiable concentrate, 0.5％ claw field aqueous solution, 0.5％ veratrine alcoholic solution, 4.1％ and 81％ ethylicin emulsifiable concentrates and over 30 compounded preparations with these botanical pesticides as the main ingredients. The registered control objects of these pesticides are mainly the pests on the vegetable and cotton, e.g. aphid, cabbage worm, plutella xylostella, helicoverpa armigera, etc.
