“…The average number of spores per 0.04 mm 2 square was multiplied by 25 to determine the total number of spores in 0.1 mm 3 (volume of the chamber = 1 mm per side × 0.1 mm deep). Finally, the number of spores per mL −1 was calculated by multiplying this value by 10 4 [45].…”

The Green Revolution led to an increased use of synthetic pesticides, causing environmental pollution. As an alternative, biopesticides made from entomopathogenic agents such as fungi have been sought. This study aimed to design and evaluate the performance of a harvester machine for efficiently collecting entomopathogenic spores of Metarhizium anisopliae and Beauveria bassiana grown on rice and corn substrates. The spore yield was estimated, and a spore count and a colony-forming unit (CFU) count were performed. Statistical analysis was conducted to compare the mean values of spores obtained from different combinations of solid substrate and fungi. The Corn-Metarhizium combination produced 34.15 g of spores per kg of substrate and 1.51 × 109 CFUs mL−1. Similarly, the Rice-Metarhizium combination produced 57.35 g per kg and 1.59 × 109 CFUs mL−1. Meanwhile, the Corn-Beauveria combination yielded 35.47 g per kg and 1.00 × 109 CFUs mL−1, while the Rice-Beauveria combination had a yield of 38.26 g per kg and 4.50 × 108 CFUs mL−1. Based on the reported results, the Rice-Metarhizium combination appears to be the most effective, yielding the highest number of harvested spores per kg of substrate. The study estimated a total cost of approximately $409.31 for manufacturing the harvester, considering only the cost of the materials. These results could potentially increase the availability and affordability of entomopathogenic fungi in integrated pest management.

The application times and doses of fresh and dry formulations of Talaromyces tratensis KUFA 0091 were evaluated for their antagonistic activity in controlling mango diseases, anthracnose and stem-end rot diseases, under eld conditions on two mango cultivars-namely, Nam Dok Mai Si Thong and Nam Dok Mai No. 4. The results show that three applications result in signi cantly reduced disease severity than two and one applications in all treatments. However, a high dose of the fresh formulation at 10 8 spores/ mL of the antagonistic fungus resulted in antagonistic activity in controlling mango diseases than the dry formulation and lower doses in both mango cultivars. Treatment of three applications at the owering, fruit-setting, and fruit-developing stages of the fresh formulation at 10 8 spores/ mL displayed the best disease reduction at 80-87%, followed by the dry formulation, which caused 75-78% disease reduction.Meanwhile, the three applications of fresh and dry formulations at 10 6 spores/mL also displayed signi cant biocontrol e cacy via 70-79% disease reduction. Its culture ltrate at 50% completely inhibited the spore germination of the anthracnose pathogen. The dry formulation also showed high e cacy suppression on post-harvest disease on mango fruits. Moreover, the antagonistic fungus showed compatibility fungicides at a label rate with propineb (1,750 ppm), azoxystrobin (250 ppm), and mancozeb (1,600 ppm). The results indicate that this fungus can act as an effective biological control or be combined with fungicides for integrated mango disease management. HighlightsFirst report of T. tratensis KUFA 0091 in controlling mango diseases under eld conditions.It show promising results in controlling the mango diseases under eld condition.It also showed potent inhibition of spore germination.
