Control of Phytophthora palmivora on postharvest papaya with Trichoderma asperellum, T. virens, T. harzianum and T. longibrachiatum

The main objective of this study was to evaluate the ability of Trichoderma aggressivum f. europaeum, T. longibrachiatum, Paecilomyces variotii, and T. saturnisporum as biological control agents (BCAs) against diseases caused by P. capsici and P. parasitica in pepper. For this purpose, their antagonistic activities were evaluated both in vitro and in vivo. We analysed the expression patterns of five defence related genes, CaBGLU, CaRGA1, CaBPR1, CaPTI1, and CaSAR8.2, in leaves. All BCAs showed a high in vitro antagonistic activity, significantly reducing the mycelial growth of P. capsici and P. parasitica. The treatments with T. aggressivum f. europaeum, T. longibrachiatum, and P. variotii substantially reduced the severity of the disease caused by P. capsici by 54, 76, and 70%, respectively, and of the disease caused by P. parasitica by 66, 55, and 64%, respectively. T. saturnisporum had the lowest values of disease reduction. Reinoculation with the four BCAs increased the control of both plant pathogens. Markedly different expression patterns were observed in the genes CaBGLU, CaRGA1, and CaSAR8.2. Based on the results, all four BCAs under study could be used as a biological alternative to chemicals for the control of P. capsici and P. parasitica in pepper with a high success rate.

“…Four antagonists [T. asperellum (SF04), T. virens (255C1), T. harzianum (THP) and T. longibrachiatum (4088)] were tested, All Trichoderma significantly (p ≤ 0.05) reduced the incidence and severity of disease. The 4088 (T. longibrachiatum) isolate was the best controller agent of P. palmivora in postharvest [7]. The purpose of this study was to determine the effectiveness of Trichoderma sp.…”

Fruit rot disease is very damaging to cacao pods, which is caused by Phytoptora palmivora. The attack rate of P. palmivora varies. In Java, losses due to this disease reduce yields by 90 %. P. palmivora is a soil–borne pathogen. It is currently included in the Kingdom Chromista. Control with fungicides is not successful at this time, the alternatives is biologis control with Trichoderma sp. This research used a Completely Randomized Design (CRD) which was arranged in factorial with two factors. The first factor was Trichoderma sp. the second factor was P. palmivora. All treatment combinations were repeated three times. Trichoderma sp. antagonist test to P. palmivora was analyzed using Analysis of Variance (ANOVA) and then further tested using a 5 % BNJ. Trichoderma sp. origin from Jember and Trenggalek districts, East Java, Indonesia were able to act as antagonists against P. palmivora with the highest inhibitory of 78 %. In comparison, the lowest inhibitory was 70 % of isolates from Jember district, East java, Indoe. Characteristics of Trichoderma sp. The origin of Trenggalek Regency and Jember Regency, East Java, Indonesia in inhibiting the growth of P. palmivora has the same species, namely Trichoderma harzianum.
