| Abstract: | The uniform and precise application of microbial particles close to the target organism and to the plant to be protected can
increase the success of a biological control treatment. The use of systems or technologies which are usually available in
agriculture could influence the acceptability of biocontrol agents by farmers, and enlarge the market. A pilot system was
realized using dripper lines, drippers, filters and other tools commonly used in irrigation and precision agriculture in the
greenhouse to evaluate their suitability for applying and distributing microbial biocontrol agents. Conidial suspensions of
marketed or marketable agents were used, i.e. Fusarium oxysporum, F. solani, Trichoderma harzianum and Paecilomyces lilacinus. The experiments carried out demonstrated that conidial suspensions (106 conidia ml−1) can pass through the drippers without causing clogging, regardless of their size, and remained viable. The term ‘microbigation’
is here proposed for this kind of microbial application technique. |
