A plant viral disease preventive composition contains an alginate, as active ingredient, having properties of:

Plant viral disease preventive alginate containing compositions

Chemicals containing an effective amount of homopolymers of dialkylaminoalkyl acrylate derivatives or dialkylaminoalkyl methacrylate derivatives or copolymers of such derivatives with ethylenically unsaturated monomers copolymerizable therewith. The chemicals exhibit a remarkable effect of preventing agricultural plants from being infected with plant virus diseases. A method for controlling the plant virus diseases is also described.

Chemicals for controlling plant virus diseases and control method

A.DELTA..sup.1 - tetrahydrophthalic anhydride is reacted with an amine in the presence of lower fatty acid. Alternatively N-(4-hydroxyphenyl)-.DELTA..sup.1 -tetrahydrophthalimide or a salt thereof is reacted with an aralkyl halide. A N-substituted-.DELTA..sup.1 -tetrahydrophthalimide compound having herbicidal activity is produced. This compound has the formula ##EQU1## wherein R' is naphthyl; phenyl; phenyl substituted by 1-3 substituents selected from the group consisting of halogen, nitro, cyano, thiocyano, carboxyl, haloalkyl, lower alkyl and alkylthio; --CH.sub.2 Y wherein Y is phenyl, naphthyl or phenyl substituted by 1-5 substituents selected from the group consisting of halogen, nitro, lower alkyl and lower alkoxyl; or ##SPC1## Wherein Z is phenyl, naphthyl, or phenyl substituted by at least one substituent selected from the group consisting of halogen, nitro, lower alkyl and lower alkoxyl.

Herbicidal N-substituted-.DELTA..sup.1 -tetrahydrophthalimide
