dc.description.abstract | Weed control is essential to ensure the productivity and quality of food production. Chemical
control is the most used, but the demand for healthier food, concern for the environment and
the health of farmers, has increased the search for other control methods. This work aims to
improve the herbicidal effect of bioherbicides produced by solid state fermentation and to
compare this technique with submerged fermentation using the fungus Diaporthe schini, in
addition to studying the use of spray drying for microencapsulation. First, solid state
fermentation was carried out to determine the best conditions for cultivation of the fungus
with herbicidal action in an absorption test on detached leaf of Cucumis sativus. The best
result found with herbicidal action in solid state fermentation was compared with submerged
fermentation, carried out through physical-chemical characterization and bioherbicidal effect.
In addition, different adjuvants for spray drying microencapsulation were studied and the
equipment parameters were optimized. All conditions were evaluated according to the postemergence
bioherbicidal effect of Bidens pilosa, Amaranthus viridis, Echinocloa crusgalli
and Lollium multiflorum. The best cultivation condition found for solid state fermentation was
40% moisture and without corn maceration water (AMM) and soybean meal (FS)
supplementation, presenting necrosis in C. sativus leaves. D. schini broth obtained by
submerged fermentation was more effective than solid state fermentation for weed control,
showing weed growth inhibition and better physicochemical characteristics.
Microencapsulation with lactose adjuvant and in the condition of the central point of spray
drying planning with an inlet temperature of 100ºC, flow of drying air 1.5 m3/min and feed
flow of 0.22 L/min showed the greatest effect bioherbicide on weeds. Submerged
fermentation combined with microencapsulation by spray drying is an important tool for the
production of D. schini bioherbicide, and may provide subsidies for further research. | |
