Independent Claim
115 words
The method for treating plants with a phytosanitary material selected from the group consisting of an herbicide, insecticide, fungicide, growth regulator, bactericide and fertilizer, comprising applying water onto the plants from a stream of water, passing the stream of water, immediately prior to application onto the plants, into contact with a solid compact containing a few to 80% by weight of said phytosanitary material selected from the group consisting of an herbicide, insecticide, fungicide, growth regulator and fertilizer, a solid non-hydrophilic filler and 20-60% by weight of a solid water insoluble starch whereby the compact disintegrates progressively into the stream of water to release said phytosanitary material into the stream for application onto the plants.
Claim 2
Independent Claim
115 words
The method for treating plants with a phytosanitary material selected from the group consisting of an herbicide, insecticide, fungicide, growth regulator, bactericide and fertilizer, comprising applying water onto the plants from a stream of water, passing the stream of water, immediately prior to application onto the plants, into contact with a solid compact containing a few to 80% by weight of said phytosanitary material selected from the group consisting of an herbicide, insecticide, fungicide, growth regulator and fertilizer, a solid non-hydrophilic filler and 20-60% by weight of a solid water insoluble starch whereby the compact disintegrates progressively into the stream of water to release said phytosanitary material into the stream for application onto the plants.
