Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
68 words
A solid phytosanitary composition compacted into single doses for agricultural application intended to be progressively disintegrated by contact with a stream of water and containing a few to 80% by weight of an active material selected from the group consisting of a herbicide, growth regulator, and fertilizer, a solid nonhydrophilic filler of which talcum is the major component and 20- 60% by weight of a solid water-insoluble starch.
Claim 2
Dependent Claim
68 words
A solid phytosanitary composition compacted into single doses for agricultural application intended to be progressively disintegrated by contact with a stream of water and containing a few to 80% by weight of an active material selected from the group consisting of a herbicide, growth regulator, and fertilizer, a solid nonhydrophilic filler of which talcum is the major component and 20- 60% by weight of a solid water-insoluble starch.
Claim 3
Dependent Claim
22 words
A composition claimed in claim 1, wherein the starch is selected from the group consisting of maize, corn, rice and potato starch.
Claim 4
Dependent Claim
13 words
A composition as claimed in claim 2, wherein the starch is not ground.
Claim 5
Dependent Claim
73 words
A process for the preparation of a phytosanitary composition of the type claimed in claim 1, comprising in a first stage mixing the active material and the filler with grinding or micronization to form a premix, and, in a second stage, mixing the premix with the starch without deformation or fragmentation of the starch grains by grinding, and compressing the mixture into single doses under a pressure of from 50 to 100 bars.
Claim 6
Dependent Claim
68 words
A solid phytosanitary composition compacted into single doses for agricultural, application intended to be progressively disintegrated by contact with a stream of water and containing a few to 80% by weight of an active material selected from the group consisting of an insecticide, fungicide and bactericide, a solid non-hydrophilic filler of which talcum is the major component and 20- 60% by weight of a solid, water insoluble starch.
Claim 7
Dependent Claim
68 words
A solid phytosanitary composition compacted into single doses for agricultural, application intended to be progressively disintegrated by contact with a stream of water and containing a few to 80% by weight of an active material selected from the group consisting of an insecticide, fungicide and bactericide, a solid non-hydrophilic filler of which talcum is the major component and 20- 60% by weight of a solid, water insoluble starch.
Claim 8
Dependent Claim
15 words
A composition as claimed in claim 1 which includes a wetting agent, dispersant or deflocculant.
