Notes on the latest use of pesticides in Edible Fungi
Edible mushroom is a common kind of vegetables in daily life, they not only have high nutritional value, but also taste delicious, and the cultivation process of edible fungi is inseparable from the use of pesticides. This article introduces in detail the matters needing attention in the use of edible fungus pesticides, let's take a look at it.
1. Prescribe the right medicine to the case
Before the use of pesticides, we should first understand the symptoms of diseases and insect pests and prescribe the right medicine to avoid the wrong use of pesticides, resulting in unnecessary effects. At the same time, we need to be familiar with the properties of agents, understand the difference between pesticides and fungicides, the two can not replace each other. For example, when edible mushroom mosquitoes and feces mosquitoes occur, trichlorfon has a special effect on the adults and larvae of mushrooms, but has poor lethality to mites. And Pleurotus ostreatus is more sensitive to dichlorvos, slightly higher concentration will produce drug damage, it is best to use trichlorfon or octane scale. While Pleurotus ostreatus is more sensitive to trichlorfon, it is best to use dichlorvos.
2. The concentration should be reasonable.
When in use, the drug concentration should be determined according to the different growth periods of fungicides, diseases and insect pests and edible fungi. Generally, the medicament concentration can be appropriately higher when stacking materials before sowing and disinfecting the mushroom room. The drug use should be strictly controlled within the safe range after sowing and before mushroom production, and the concentration should be lower in the process of fruiting body growth and development. For example, when adding acaricides to control mites and other pests, 500x liquid can be used before stacking to produce mushrooms, but it should be reduced to 1000 times liquid when drugs must be used in the fruiting body stage.
3. the use of drugs is strictly prohibited during the mushroom period.
In the use of pesticides, must be used before mushrooms, or after the mushrooms will be used, do not use drugs during the mushroom period. Because the cultivation cycle of edible fungi is short, drugs are easy to remain and cause food poisoning, which will have a serious impact on product circulation and consumption, and some pesticides will also cause drug damage to edible fungi.
4. Select agents with high efficiency, low toxicity and low residue.
In the choice of pesticides, try to choose agents with high efficiency, low toxicity and low residues, and prohibit the use of highly toxic pesticides. The more commonly used fungicides are carbendazim, chlorothalonil, Dysen zinc, methyl thiophanate, Bordeaux solution, stone sulfur mixture and so on. Commonly used pesticides are phoxim, dichlorvos, trichlorfon, killing chrysanthemum vinegar and so on. No matter when spraying, mixing, disinfection, it is strictly forbidden to use highly toxic, residual for a long time, such as organic mercury, organophosphorus and so on. At the same time, we should also pay attention to the alternate use of drugs, so as not to produce drug resistance and reduce the efficacy.
The above is an introduction to the matters needing attention in the use of pesticides in edible fungi. I hope I can help you. If you want to know more about it, please follow us.
