Pest Control of Pleurotus ostreatus

Pleurotus ostreatus has strong resistance and is easy to cultivate. According to the practice of cultivation and the situation of popularization in recent years, the disease which seriously harms the growth of Pleurotus ostreatus has not occurred. However, before mushroom production, we will occasionally see some miscellaneous bacteria, such as ghost umbrella, disk fungus, naked cover mushroom and other competitive bacteria, of which ghost umbrella is more common. In the cultivation process of Pleurotus ostreatus, the more common pests are mites, jumping insects, mushroom mosquitoes, ants, slugs and so on. The main prevention and control measures are as follows:

The main results are as follows: (1) Ghost umbrellas often occur on the bacterial bed with poor mycelium growth or when using poor quality rice straw as culture material. The main prevention and control measures are:

① straw is required to be fresh and dry. Before cultivation, let it be exposed to the hot sun for 3 days and use the sun to kill the spores of Ghost umbrellas and other miscellaneous bacteria.

In the process of ② cultivation, we should master the water content of the culture material in order to facilitate the robust growth of hyphae and make the hyphae dominate absolutely.

③ and Pleurotus ostreatus both belong to mushrooms, which grow in the same environment, so it is difficult to eliminate them completely. If their fruiting bodies are found on the fungus bed, they should be removed as soon as possible.

(2) Control measures of common insect pests

① chooses the site and forbids cultivation in places where there are many termites. It is best not to continue cropping for many years in order to avoid the breeding of pests.

During the cultivation of ②, 0.5% dichlorvos cotton balls were dipped around the bacterial bed to ward off pests such as mites, jumping insects and mushroom mosquitoes. You can also put newspapers, waste cloth and dipped in sugar on the bacterial bed, or trap mites such as freshly roasted pig bones or oil cake powder. For jumping beetles, a mixture of 1 part of honey, 10 parts of water and 2 parts of 90% trichlorfon can be trapped and killed.

Ant nests found in ③ farms or haystacks should be killed by spraying in time. If the red ant, you can use the red ant net powder scattered in the place where there is an ant road, ants eat, can die the whole nest, the effect is very good. If it is a white ant, it can be sprayed into the nest with 3g of termite powder, which can be effective after about 5Mel for 7 days.

④ slugs like to be born in a dark and humid environment, so they should choose cultivation grounds with higher terrain, convenient drainage and irrigation, and shade of 50%, 70%. For the prevention and control of slugs, artificial hunting can be carried out by making use of its rule of sunshine and rain, or 10% salt water can be sprayed around the site to drive slugs away.

⑤ in the outdoor cultivation field, rats often make nests in the haystack, destroying the bacterial bed and injuring the hyphae and mushroom buds. The method of running out of food or trapping can be used in the early stage. Rat blood can also be dripped around the cultivation ground and beside the bacteria bed, so that other mice can see and escape.
