Soil amendment with crustacean chitin used alone or with Pseudomonas aeruginosa Bacillus subtilis significantly (p<0.05) reduced infection of Rhizoctonia solani Fusarium solani on sunflower and R. solani on chickpea. Crab chitin used alone or wítfiř. aeruginosa or B. subtilis completely controlled the infection of Macrophomina phaseolina on chickpea. Prawn or shrimp powder used 1% w/w of soil was found phytotoxic on chickpea but not on sunflower. Maximum fresh weight of shoot was produced by P. aeruginosa used with shrimp powder in sunflower and with crab chitin in chickpea. P. aeruginosa produced greater plant height in chickpea used with shrimp chitin.

Potraktowanie gleby chityną otrzymaną ze skorupiaków - samą lub łącznie z Pseudomonas aeruginosa lub Bacillus subtilis - redukowało istotnie (p<0.05) infekcję Rhizoctonia solani i Fusarium solani na słoneczniku i R. solani na cieciorce. Chityna z krabów użyta osobno lub z P. aeruginosa lub B. subtilis całkowicie hamowała infekcję Macrophomina phaseolina na cieciorce. Proszek z ślimoraczka lub krewetki użyty w stężeniu 1% (wagowo) doglebowo był fitotoksyczny dla cieciorki, ale nie dla słonecznika. Największą świeżą masę pędów produkował słonecznik w efekcie użycia P. aeruginosa łącznie z proszkiem z krewetek, a cieciorka - po użyciu chityny z krabów. Najwyższe rośliny cieciorki otrzymano w wyniku użycia chityny z krewetek.
