Methomyl Insecticide Selective Phytotoxicity on Sweet Corn Hybrids and Inbreds Having the Texas Male Sterile Cytoplasm1
Year: 1977
Type: article
Abstract: Methomyl insecticide (Lannate 90 wp) was selectively phytotoxic on hybrids and inbreds of sweet com ( Zea mays L.) having the Texas male sterile cytoplasm (T-msc). In field and greenhouse tests, phytotoxicity was visible at leaf tips and margins 2 days after a foliar application of 300 ppm methomyl. In the greenhouse, a pre- or postemergence application of methomyl, 75 mg/kg soil resulted in severe necrosis, chlorosis, and eventual death of the seedlings. None of 100 hybrids and inbreds with normal cytoplasm and 4 other different sources of sterile cytoplasm showed any visible injury following a foliar or soil application of methomyl.
