1. WO1991007975 - NEMATOSTATIC TRICHOTHECENE COMPOSITIONS

Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

We Claim:
1. A composition to prevent plant damage by nematodes which comprises a trichothecene.
2. The composition of Claim 1, further comprising about 10 to about 20 volume percent of a nonionic surfactant.
3. The composition of Claim 1 wherein said trichothecene is selected from the group consisting of roridin A, verrucarin A, HT-2 toxin, T-2 toxin,
trichoverroids, diacetoxyscirpenol, verrucarol, acetyl-T-2 toxin, neosolaniol, tetracetyl T-2 toxin, T-2 tetraol, T-2 triol, diacetylnivalenol and crotocin.
4. A method for inhibiting nematode infection of plants, comprising:
applying to said plant, or to the soil
surrounding said plant, an effective amount of a
trichothecene to produce a nematostatic effect in said plant.
5. The method of Claim 4 wherein said
trichothecene is selected from the group consisting of HT-2 toxin, T-2 toxin, trichoverroids, verrucarol, acetyl T-2 toxin, T-2 tetraol, diacetoxyscirpenol, neosolaniol, trichothecin, nivalenol and
diacetylnivalenol.
6. The method of Claim 4 wherein said
trichothecene is selected from the group consisting of verrucarin A, roridin A and crotocin.
7. The method of Claim 4 wherein said
trichothecene is applied at a concentration of about 1 to about 1,000 ppm.
8. The method of Claim 6 wherein said
trichothecene is roridin A, said roridin A being applied at a concentration of about 1 to about 1,000
micrograms/ml.

9. The method of Claim 8 wherein said roridin A concentration is about 7.5 micrograms/ml.
10. A method for inhibiting nematode infection of plants, comprising applying about 1 to about 1,000 ppm of roridin A to a plant, or to the soil surrounding said plant, to produce a nematostatic effect in said plant.
