초록
기린계(有機燐系) 살충제(殺蟲劑)인 dichlorvos 유제(乳劑)(50%), fenthion 유제(乳劑)(50%), fenitrothion 유제(乳劑)(50%) 및 phenthoate 유제(乳劑)(47.5%)의 뽕잎중(中) 잔류성(殘留性)과 이들 잔류수준(殘留水準)이 누에에 대한 사충률(死蟲率) 및 수견양(收絹量)에 미치는 영향(影響)을 조사(調査)하기 위하여 무강우조건하(無降雨條件下)에서 포장시험(圃場試驗)을 실시(實施)하였다. Fenitrothion, fenthion, phenthoate의 뽕잎중(中) 반감기(半減期)는
The present study was aimed to investigate persistence of dichlorvos EC, fenitrothion EC, fenthion EC, and phenthoate EC in and on mulberry leaves with special reference to silkworm mortality and cocoon production under greenhouse condition. The halflives of fenitrothion, fenthion, and phenthoate in and on mulberry leaves were ranged from two to three days, while that of dichlorvos was less than 9 hours. The insecticide residues in and on mulberry leaves persisted longer in spring cropping season than in autumn cropping season. Elapsed periods from last application of each insecticide to leaf harvest for silkworm feed and maximum residue limits for safe cocoon production as well as relations between insecticide residues in and on mulberry leaves and silkworm mortality were produced.
