First study of hormesis effect on mushroom cultivation

Abstract

The use of fungicides is common in mushroom cultivation, but no study was carried out applying reduced doses of fungicides in order to increase yield, taking account the hormesis effect. The aim of this manuscript was to verify the effects of different concentrations of fungicides to stimulate the productivity of different strains of Agaricus bisporus. Two stages were developed, an in vitro study to define the best concentration to be applied in the second experiment an agronomic study, which consisted of the application of the selected fungicides, in their respective concentrations, in an experiment carried out in the mushroom chamber. Clearly, the result of the hormesis effect on mushroom cultivation can be verified. The results obtained in the 1st stage of the study (in vitro) were not always reproduced in the 2nd stage of the study (in vivo). The kresoxim methyl active ingredient may be an important chemical agent, while strain ABI 15/01 may be an extremely important biological agent to increase yield in the study of hormesis effects.

Postharvest of fresh white shimeji mushroom subjected to UV-C radiation

“…It represents a dose-response phenomenon characterized by low-dose stimulation and high-dose inhibition, which can be graphically depicted as either an inverted U-shaped dose-response curve or a J- or U-shaped dose-response curve [ 38 ]. A similar result has already been observed in edible mushrooms Agaricus bisporus after the application of low fungicide doses [ 39 ].…”

Pleurotus spp. cultivation on Brachiaria sp. straw treatment with alkaline water

“…The yield parameters of the fruit bodies were evaluated based on the yield (Y), biological efficiency (BE), number of mushrooms (NM), and weight of mushrooms (AFB). 12 , 13 , 14 , 15 For Y, the basidiocarp fresh weight was divided by the compost fresh weight, multiplied by 100, and expressed as a percentage. BE was calculated as the basidiocarp fresh weight divided by the compost dry weight, multiplied by 100, and expressed as a percentage.…”
