Abstract
A method of controlling the population of a first microorganism at a foliar locus by preferentially enhancing the population of a second microorganism at said locus, comprises applying to the locus an amount of a durable selective habitat enhancer which substantially preferentially potentiates growth of said second microorganism with respect to said first microorganism. The durable selective habitat enhancer preferably comprises a substantially water-insoluble, weather resistant polymeric substrate and a binder which increases the durability of the habitat enhancer. The second microorganism can be endogenous to the foliar locus or exogenously applied. Chitin and cellulose are preferred habitat enhancers.

A method of controlling the population of a first microorganism at a foliar locus by preferentially enhancing the population of a second microorganism at said locus, comprising applying to the locus an amount of a durable, substantially water-insoluble polymeric substrate having a solubility in water (20.degree. C. of at most 1% which has been selected for being preferentially biodegraded by said second microorganism, whereby growth of said second microorganism is substantially preferential to that of said first microorganism, and wherein said polymeric substrate is applied in admixture with a binder which increases its durability.
A method of controlling the population of a first microorganism at a foliar locus by preferentially enhancing the population of a second microorganism at said locus, comprising applying to the locus an amount of a durable, substantially water-soluble polymeric substrate having a solubility in water (20.degree. C.) of at most 1% effective as a selective habitat enhancer which has been selected for substantially preferentially potentiating growth of said second microorganism with respect to said first microorganism, and wherein said polymeric substrate is applied in admixture with a binder which increases its durability.
