Claims20
A Bacillus thuringiensis isolate active against nematodes, said isolate selected from B. thuringiensis strain PS-17, B. thuringiensis strain PS-33F2, B. thuringiensis strain PS-52A1, B. thuringiensis strain PS-63B, and B. thuringiensis strain PS-69D1.
A process for controlling nematodes which comprises contacting said nematodes with a nematode-controlling effective amount of a toxin produced by a B. thuringiensis isolate selected from B. thuringiensis strain PS-17, B. thuringiensis strain PS-33F2, B. thuringiensis strain PS-52A1, B. thuringiensis strain PS-63B, and B. thuringiensis strain PS-69D1.
A process for treating an animal hosting a nematode which comprises administering to said animal host a nematode-controlling effective amount of a toxin produced by a B. thuringiensis isolate selected from B. thuringiensis strain PS-17, B. thuringiensis strain PS-33F2, B. thuringiensis strain PS-52A1, B. thuringiensis strain PS-63B, and B. thuringiensis strain PS-69D1.
