Design of Safety Parameters for Selecting the Pesticide Used in the Tea Garden

Chen Zongmao(Tea Research Institute,Chinese Academy of Agricultural Sciences,Hangzhou)  
A model of safety evaluation for selecting the pesticide used in the tea garden wassuggested by the author according to the experimental results of the degradative dynamicsof more than 20 pesticides on the tea bush.Among the main factors influencing thedegradation of pesticides and the safety of human from the pesticide was applied onthe tea bush to the pesticide residue entered the human body with the tea infusion,5 physical,chemical and biological parameters of pesticides were selected as thesafety indexes by the author in the purpose of selecting the pesticide suitable in the teagarden.It also would be useful in the structural design of synthesizing the pesticidepurposefully.It comprises the following 5 selective parameters and each of which issub-divided into 4 classes.(1)Half-life(HL_(50))on fresh tea leaves:1st class0.6days;2nd class 0.61-1.5 days;3rd(?)class 1.51-3.0 days;4th class3.0 days.(2)Vapour pressure of pesticide(mm Hg,20-25℃):1st class1×10~(-5);2nd class1×10~(-5)—1x10~(-6);3rd class 1x10~(-6)—1x10~(-7);4th class1×10~(-7).(3)Watersolubility of pesticide(ppm,20-25℃):1st class1;2nd class 1-100;3rd class101-200;4th class200.(4)ADI value(Acceptable Daily Intake)of pesticide(mg/kg.day):1st class0.01;2nd class 0.005-0.01;3rd class 0.001-0.0049;4th class0.001.(5)Oral LD_(50)of acute toxicity in rats(mg/kg):1st class500;2nd class 101-500;3rd class 31-100;4th class30.The evaluation ofthe safety of pesticides is based upon the cumulative value of the above 5 parameters.It is showed that the lower the cumulative values,the safer the pesticide.If thecumulative value of a pesticide is over 12,it can not be used in the tea garden.
