In 1964 and 1965, six bifunctional aziridine chemicals compared as sprays on caged cotton as sterilants for control of Anthonomus grandis Boheman. Comparisons were made of the numbers of sterile eggs found, egg-punctured squares that developed to bolls, and the total produced. Phytotoxicity to plants was noted. order of decreasing effectiveness the chemicals were: OM 53264 (N, N’-(4-methyl-m-phenylene) bis-(1-aziridinecarwere boxamide)), OM 53061 (1-[bis(l-aziridinyl) phosphinyl]-3 (3,4-dichlorophcnyl) urea), apholate, OM 53139 (N-N’- hexamethylenebis (I-aziridinecarboxamide), OM 53386 (N, N’- (4-methyl-m-phenylene) bis 2-methyl-I-aziridinecarbolls In boxamide), and OM 2797 (3.9-bis (I-aziridinyl)-2.4,8,10-tetraoxa-3,9-diphosphaspiro[5.5]undecane 3,9-dioxide). |
