Furobenzopyran derivatives of the general formula (I): ##STR1## in which R.sup.1 is a lower alkyl group, R.sup.2 is a lower alkyl group, lower alkoxy group, halogen atom or lower alkyl group substituted by a halogen atom, R.sup.3 is a lower alkyl group, lower alkoxy group, halogen atom, lower alkyl group substituted by a halogen atom, phenoxy group or benzyloxy group, R.sup.4 is a hydrogen atom or lower alkyl group and m and n are any integers between 0 and 4, have an excellent herbicidal activity on weeds and are completely selective to crops such as paddy rice, soybeans and cotton.

Furobenzopyran derivatives, process for preparation of same and

Application of a rice blast control agent containing an isothiazolecarboxylic acid derivative of the below-described formula, which shows excellent activity against rice blast (Pyricularia oryzae) in rice cultivation, to the water surface of a paddy rice field results in the absorption of the derivative through roots of rice plants, so that the resistance of the rice plants can be enhanced. ##STR1## wherein R.sup.1 and R.sup.2 independently mean a hydrogen or halogen atom or a particular group, and Y stands for an OR.sub.3 group (R.sup.3 being a hydrogen or alkali metal atom or a particular group), an NHR.sup.4 group (R.sup.4 being a hydrogen atom or a particular group), or a morpholino group.
