Forty-six farmers were patch tested to determine whether their dermatitis was secondary to an occupational allergen. Twenty-eight had a positive patch test of which 23 were thought relevant (definite or probable). In 20 of these cases, the allergen(s) was considered to be work related (define or probable). The common allergens were pesticides (N-(1,1,2,2-tetrachloroethylthio) -4-cyclohexene-1,2-dicarboximide (captafol), ethylenebis (dithiocarbamato) manganese (maneb) and copper sulfate), rubber compounds (N-isopropyl-N-phenyl-4-phenylenediamine (IPPD) and 4-phenylene diamine base) and sunscreen chemicals.

The effect of two herbicides (paraquat and 2,4-dichlorophenoxybutyric acid) and two fungicides (mancozeb and captafol) was studied on the growth of Flagellospora penicillioides, Lunulospora curvula and Phalangispora constricta using the poisoned-food technique. The pesticides did not produce any inhibition of growth at concentrations up to 5 mg/l. The required concentration to bring about total inhibition of growth varied among the chemicals and the cultures. The herbicides produced a slight enhancement of culture growth at concentrations ranging from 1 to 25 mg/l.
