Early winter edible fungi to prevent pests
In the early winter season, the widening of the temperature difference caused the pests outside the mushroom shed to enter the shed, which made the difficulty of prevention and control even more difficult. In actual production, many mushroom farmers do not pay attention to prevention, and once pests occur, a large number of chemical drugs are used to kill them quickly, and the results are often difficult to achieve.
First, physical prevention
Since there are live insects or eggs in the raw materials, do not directly carry out the sowing of raw materials, at least after fermentation treatment, preferably by clinker cultivation or for seed production. Strictly check whether the strain is infected with insects. The purchased strains should be carefully checked before transfer to prevent the inoculation of insects. Encapsulated insect-proof nets such as mushroom vents and import and export to prevent adult insects from flying in. Spread lime spacers at the vents and inlets to prevent reptile pests from entering.
Second, drug prevention
1. Add phoxim and other drugs when mixing. The dosage is generally about 100 ml per 1000 kg of dry material. When the raw material is cultivated, it can be added with the mixture. The best time for fermenting the cultivation is the last time before turning over. Adding, through high temperature and stuffy pile, the insecticidal effect is very good.
2, within a certain distance outside the shed, after cleaning up the waste, you can use high-efficiency insecticides, such as trichlorfon, to kill insects and cut off pests.
3, outside the shed and shed vents, import and export, use cypermethrin high-efficiency low-residue drugs to spray, in order to prevent reptiles into the shed.
4, mushroom sheds can generally be sprayed with cypermethrin and other drugs to kill insects, use avermectin to kill aphids, mushroom mosquitoes, mushroom fly pests, conditional use of high-efficiency insect repellent to repel.
