<p>The effect of certain agricultural chemicals is improved by co-administration of them with one or more additives that modify the uptake of the chemical by modifying physico-chemical properties of the leaf or that alter the physical relationship between the agricultural chemical and the leaf surface such that the uptake of the agricultural chemical is altered beneficially, e.g. by temporarily holding the agricultural chemical in a layer on the leaf surface during a period when it is not needed by the plant. Compositions contain one or more of the agricultural chemicals and one or more of the additives, and the harvest of a given crop can be improved by applying it to one or more of the agricultural chemicals and one or more of the additives simultaneously or within up to 15 days of one another. The compositions may be made up with purgatives or emetics to reduce toxicity.</p> |
