英语. Disappearance of the pesticide pyrazophos from Soultanina (Thompson seedless) grapes was studied. Vines, covered and uncovered, were sprayed with the pesticide and samples were collected and analyzed at regular time intervals. Two lots were collected (the first, two hours after spraying and the second 20 days later) and stored in a commercial refrigerated room. Disappearance of the pesticide was studied for about 50 days for the grapes on the vines and 130 days for the grapes stored in the refrigerated room. Half-lives of the pesticide pyrazophos were found to be: 17 days for uncovered grapes on the vines, 32 days for covered grapes on the vines and 151 days for refrigerator-stored grapes

I campioni sono stati raccolti e analizzati a intervalli di tempo regolari. Le due partite, raccolte la prima un'ora dopo il trattamento e l'altra dopo 20 giorni, sono state conservate in una cella refrigerata. La scomparsa del pesticida e' stata studiata durante 50 giorni per l'uva sulle piante e 130 giorni per l'uva conservata. I periodi di semivita del pesticida pyrazophos sono, rispettivamente: 17 giorni per l'uva sulle viti allo scoperto, 32 giorni per l'uva sotto copertura e 151 giorni per l'uva conservata in cella refrigerata
