How to effectively control edible fungus pests
The management of insect pests—such as mushrooms, mushroom worms, cockroaches, nematodes, and others—is a major challenge for mushroom farmers during the cultivation of edible fungi. These pests can easily infiltrate the growing medium, feeding, reproducing, and hiding in hard-to-reach areas. Detecting them is often difficult, and once they cause damage, it's challenging to eliminate them effectively. With increasing global demand for pollution-free, safe, and green agricultural products, traditional pesticides are being more strictly regulated. As a result, farmers must focus on prevention rather than reactive measures. However, it's also important not to ignore existing infestations. Here are several practical methods that experienced mushroom growers have successfully used to manage pest problems:
1. **Use fermentation or clinker-based cultivation** as much as possible to reduce pest populations at the source. For example, when preparing compost for Agaricus bisporus, adding 0.5% salt, 3% lime, and 5–8% turfgrass can help repel and prevent pests from entering the growing medium.
2. **Sterilize empty sheds before introducing spawn bags or culture materials**. A mixture of 0.3% dichlorvos and 0.1% cypermethrin can be sprayed, or aluminum phosphide (10g/m³) can be used for fumigation. When the temperature reaches around 48°C, this method achieves an insecticidal effect of 95–100%. Note: Aluminum phosphide is highly toxic and should be handled with caution. It is effective against nematodes, mushroom flies, and fungus gnats.
3. **Spray a 1–2% detergent solution** on the surface of the planting material. This solution has strong contact effects on adult and larval stages of mushroom flies and other pests.
4. **Leverage the light and cool-seeking behavior of pests** by spraying a liquid onto translucent plastic films. Covering the beds with these films and spraying 1–2 times daily, or even up to 4 times, can effectively kill flying insects.
5. **Install 15W incandescent or blacklight bulbs** inside the mushroom house. Place a container of water underneath and add a few drops of kerosene. This method works well for killing fungus gnats, fruit flies, and other flying pests.
6. **Use sweet and sour liquid traps** to lure and kill pests. Mix sugar, vinegar, alcohol, dichlorvos, and water in a ratio of 2:3:4:1:90. Soak gauze or cotton balls in the solution, wring them out, and place them on the growing surface. Pests attracted by the smell will climb onto the cloth and get poisoned.
7. **Create bait mixtures** that attract pests. For instance, combine vinegar, sugar, insecticide, and fried yellow bran in a ratio of 1:5:10:84. Spread the mixture around the mushroom bed. Alternatively, apply a layer of ash mixed with pyrethrum (1g/m²) on the surface. This method is effective against flies, mushroom mosquitoes, and nematodes.
8. **In cold seasons**, use a "kill and remove" approach. On sunny mornings, spray the bed with a sweet and sour solution, cover it with a film, and open the straw curtain. As temperatures rise, pests will come to the surface. In the afternoon, remove the film, collect the pests, and wash them away. Then, apply high-dose but low-toxicity insecticides. Repeating this process 3–5 times can significantly reduce pest infestations.
By combining these strategies, farmers can effectively control pests while maintaining the safety and quality of their edible fungi. Prevention remains key, but proactive and targeted interventions are essential when infestations occur.
