Estudo da concentração de conídios de Trichoderma em meio sólido

Abstract

The application of Trichoderma has become popular in recent years. The fungus shows promise in several agricultural applications and is most commonly found in soils where the climate is tropical or temperate. Its popularity is due to the fact that its positive characteristics encourage the interest of producers, which arises because, in addition to efficiently controlling pathogens, some of its species are able to enhance plant growth due to the production of hormones and nutrients. It is also important to carry out tests and trials that analyze the best results of conidia concentration produced by fungi of the genus Trichoderma. This work aimed to analyze the concentration and conidia of the fungus and biocontroller Trichoderma, through tests, which were carried out on a farm in the municipality of Unaí-Mg. The research and experimentation was based on a sample in which the production of conidia was evaluated at four different opening times of the solid fermentation bags (T1 - 0h, T2 - 24h, T3 - 48h and T4 - 72h). It was verified, from the four different times, that the results of the averages of the evaluated treatments referring to the spore count, did not present statistically significant differences.
