Appeal No. 2000-1568
Application 08/695,249
protozoa, nematodes and pathogenic components of said agents; (2) a water absorbent
material; (3) a membrane stabilization agent; and (4) a granulating agent, wherein the
biocontrol agent is in aqueous suspension, wherein the water absorbent material binds
with available water in the suspension of biocontrol agent, wherein the amount of
membrane stabilization agent is in the range of about 10-65% by dry weight of the
complete formulation and wherein the aqueous suspension of biocontrol agent, the water
absorbent material, the membrane stabilization agent and the granulating agent exist in
said formulation as a blended mixture.
9. A method of preparing a biocontrol agent in a granular formulation, wherein
said biocontrol agent is pathogenic upon contact or ingestion by an agricultural pest
selected from the group consisting of insects, weeds, crop diseases, and detrimental
nematodes and wherein said agent is selected from the group consisting of bacteria,
fungi, viruses, microsporidians, protozoa, nematodes and pathogenic components of said
agents, comprising the steps of:
a. blending said biocontrol agent in aqueous suspension with a water
absorbent material and a membrane stabilization agent into a dough;
b. blending the dough of step (a) with a granulating agent to reduce said dough
to discrete granules;
c. recovering the granules of step (b).
17. The method of Claim 9 wherein the granules recovered in step (c) are
redispersed in water to yield a sprayable formulation.
