zonata has developed resistance against trichlorfon
, malathion, bifenthrin, l-cyhalothrin and spinosad, while they still remained susceptible to methomyl.
The Italian laboratory analyzed foods of plant origin for several additional organochlorine pesticides and also tested for several organophosphorus pesticides and three related products: phosalone, trichlorfon
, and thiram.
Figure 2 shows the I[C.sub.50] (concentration for 50% inhibition) values of fenthion, fenthion sulfoxide, fenthione sulfone, fenitrothion, fensulfothion, EPN, trichlorfon
, and malathion against the androgenic activity of DHT at a concentration of [10.sup.-10] M.
The correlation coefficients ranged between 0.69 (permethrin) and 0.85 (trichlorfon
(c)Fewer than five cases used captan, coumaphos, 2,2-dichlorovinyl dimethyl phosphate IDDVP), permethrin (for animals), and trichlorfon
. (d) Category boundaries set at the median cumulative lifetime days of use of each pesticide among applicators who used them (i.e., both cases and controls).
These active ingredients include permethrin, carbofuran, acephate, carbendazim, omethoate and trichlorfon
among others, says the 34-page report titled 'Pesticides in Kenya: Why our health, environment and food security are at stake.'

Among these, Deltamethrin, Ivermectin, Cypermethrin, Fipronil, Trichlorfon
and Dichlorvos are commonly used.
A method was developed for trichlorfon
residue as dichlorovos analysis by GC-uECD.
