Control methods for small fungal infections on shiitake mushroom logs
During the cultivation of edible mushrooms, small fungi such as Trichoderma spp., Penicillium spp., Aspergillus spp., and slime molds infect substitute substrate cultivation. Under conditions suitable for their growth and reproduction, they can likewise infect segment logs. The morphological characteristics and occurrence patterns of these small fungi have been described for oyster mushrooms and button mushrooms. Because cultivation forms differ, the control methods also differ slightly: if small fungal infection is found on any part of the mushroom log, a kerosene blowtorch can be aimed at the pathogen to burn it to death, and then the infected area should be coated with a layer of 5%-10% limewater or

How to prevent the occurrence of small silkworms, "Fusangyi" silkworms and lost silkworms
The level of silkworm cocoon yield is not only related to the weight of a single cocoon, but also depends to a large extent on the number of silkworms per sheet of eggs. Therefore, effective measures should be taken during rearing to prevent the occurrence of small silkworms, "Fusangyi" silkworms and lost silkworms. The specific measures are as follows: 1. Carefully select good leaves. For collecting newly hatched silkworms and for the leaves used for 1st to 2nd instar silkworms, choose mulberry leaves that are suitably mature but on the tender side, fresh in leaf quality, and with a moisture content of no less than 75%. Avoid using old leaves and immature leaves, otherwise small silkworms are easily formed. During the middle feeding stage and the peak feeding stage, fresh and relatively tender mulberry leaves should also be chosen to feed the silkworms. 2. Suitable temperature and humidity. The optimum room temperature for 1st to 2nd instar silkworms
