ABSTRACT Despite the favorable edaphoclimatic conditions for avocado production in Brazil, diseases such as root rot caused by the pathogen Phytophthora cinnamomi compromise the crop. With the aim of managing root rot in avocado, the present study aimed to evaluate chemical and biological control with isolates of Trichoderma spp. and Pseudomonas fluorescens. Thus, three assays were conducted to assess: (i) mycelial inhibition of P. cinnamomi by isolates of Trichoderma spp. and P. fluorescens from different crop systems; (ii) effect of autoclaved and non-autoclaved metabolites of P. fluorescens, and (iii) chemical or biological treatment of avocado seedlings on the control of root rot under field conditions. The isolates of Trichoderma spp. from maize cultivation soil and the commercial products formulated with Trichoderma presented greater antagonism (p <0.05) to the pathogen P. cinnamomi in the in vitro tests. Similarly, non-autoclaved metabolites of P. fluorescens presented antagonistic potential to control P. cinnamomi. Under field conditions, the fungicide metalaxyl and the bioagents showed effectiveness in controlling P. cinnamomi, as well as greater root length and mass. Results demonstrated potential for the biological control of avocado root rot with Trichoderma spp. and P. fluorescens.

Study Results

Root rot of chickpea (Cicer arietinum L.) is caused by Fusarium solani. This paper describes the efficacy of Trichoderma spp. against sensitive and resistant isolates of F, solani by dual culture method under invitro conditions. Trichoderma virens, T. atroviride, T. viride, T. harzianum, T. koningiopsis, T. stilbohypoxyli,and T. pseudokoningii species were used for the antagonistic study. Results indicate that all Trichoderma species showed great antagonistic activity. But among them, T. virens, T. atroviride, T. viride showed 90% and 80 % antagonistic activity than others in case of a sensitive isolate of test fungus. The resistant isolate of the pathogen was restricting the antagonism to some extent.

This study examines the effectiveness of mycorrhizal Rhizoctonia resistance induction in Phalaenopsis amabilis against Fusarium sp. Fusarium solani is known as pathogens that attack many orchids P. amabilis (Chung et al., 2011) compared to other pathogenic fungi. Attack of Fusarium sp. will cause rot and yellow colored leaves. Until now there has been known as a biological control orchid against Fusarium sp. In this study tested the endurance locations in Sleman and Surakarta to see the effectiveness of a good orchid growth induced by Rhizoctonia mycorrhizal or not to attack by Fusarium sp. The results of the study showed that mycorrhizal Rhizoctonia able to inhibit the attack of Fusarium sp. It is shown by the value of the index of disease resistance  (DSI) in P. amabilis orchid mycorrhizal Rhizoctonia induced lower than that not induced. Mycorrhizal Rhizoctonia induction results in Sleman provide a more real than mycorrhizal Rhizoctonia induction in Surakarta.
