A method is disclosed for the control of nematodes in agricultural crops which comprises applying to the situs of infestation a compound of the formula
wherein Xl and X2 are each halogen atoms; R1 is hydrogen, lower alkyl, or di(lower)alkyl phosphate; each R is hydrogen, halogen, lower alkyl or nitro; and n is 0, 1, or 2. Preparation and nematicidal utility for the compounds are described and exemplified. When R1 is other than hydrogen or at least one R on the thiophene ring is nitro, advantageously at the 3 or 5 position of the thiophene ring, the compounds of the above formula are novel.
本发明公开了一种用于控制农作物中线虫的方法,该方法包括向侵染部位施用式中的化合物
其中 Xl 和 X2 各为卤素原子;R1 为氢、低级烷基或磷酸二(低级)烷基;各 R 为氢、卤素、低级烷基或硝基;n 为 0、1 或 2。对这些化合物的制备和杀线虫作用进行了描述和举例说明。当 R1 不是氢或噻吩环上至少有一个 R 是硝基时(最好是在噻吩环的 3 或 5 位),上述式子的化合物是新颖的。
