The Prevention and Control of Mushroom Trichoderma
Trichoderma is the most dangerous of all the bacteria that harm the growth of shiitake mushrooms. Trichoderma, also known as green mold, is widely distributed in various plant residues, soil and air. Trichoderma has no ideal radical drug so far. Therefore, the creation of an ecological environment suitable for the growth of mycelium of mycelium is not conducive to the reproduction of Trichoderma, and it is the fundamental measure to control the damage. In the event of trichoderma damage, it is necessary to immediately ventilate and reduce humidity in order to suppress the expansion of Trichoderma. After the culture material in the fungus stage is infected, the injection of liquid can be used to suppress the expansion of Trichoderma. The commonly used liquid is 5%. Stone carbonic acid, 2% formaldehyde, 1:200 times 50% carbendazim, 75% thiophanate-methyl, lime water with a pH of 10, in addition, the white surface of the pollution is sprinkled with ash and the control effect is also very good.
