Claims16
A composition for controlling insects and nematodes which comprises:
- (a) a nitrophenyl ##STR6## pyrone wherein x is an integer between 0 and 8 and wherein R.sub.1 is selected from the group consisting of a direct bond, --CH.dbd.CH-- and --CH.dbd. furanyl substituents;
- and
- (b) an agricultural carrier other than water alone, wherein the pyrone is present in an amount in the carrier which provides between about 0.001 and 100 ppm by weight sufficient to control the insects and nematodes.
A composition for controlling insects and nematodes which comprises:
- (a) a compound selected from the group consisting of spectinabilin, stereoisomers of spectinabilin, aureothin, luteoreticulin and griseulin and isomers thereof;
- and
- (b) an agricultural carrier other than water along, wherein the compound is present in an amount in the carrier which provides between about 0.01 and 100 ppm by weight sufficient to control the insects and nematodes.
