Nematocidal activity of hydroalcoholic extracts of spent substrate of Pleurotus djamor on L larvae of Haemonchus contortus.

The objective of this study was to evaluate and compare the in vitro lethal effect of the hydroalcoholic extract of the spent substrate of Pleurotus djamor ECS-123, obtained at 15 days of colonization (SPS) and at the first (SPS1) and second (SPS2) harvests, against infective larvae L of Haemonchus contortus. The in vitro lethal effect was evaluated by the L larval mortality test (LM) using six concentrations: 1.25, 2.

Agaricus bisporus production on substrates pasteurized by self-heating.

The aim of this work was to determine if the self-heating pasteurization procedure is technically applicable to the cultivation of Agaricus bisporus. Firstly the substrates alone (corncob, Pangola grass and a mixture of both ingredients with wood shavings) were tested. Two supplementation trials were then undertaken using soybean, wheat bran, sheep manure, sesame seed, black bean and chia.
