Pay attention to the control of edible insect pests

In June, the summer cultivation of edible fungi is underway. Part of the cultivation in spring has not yet been completed. In particular, in the spring and winter, the mushroom bags continued to grow have different degrees of diseases and insect pests. According to the mushroom farmer, individual cultivation fields were eroded and part of the mushroom farmers did not dare to continue feeding.
The insect pests in the production of edible fungi include mushroom mosquitoes, mushroom flies, and hoppers, cockroaches, and the like. Generally, they do not cause the danger of extinction. However, in the past two years, they have become increasingly serious, becoming the second largest problem after pollution. For pest control, we must adhere to the principle of "prevention first, prevention and prevention of both", that is, pre-production and prevention in advance, timely detection in management, and once complete destruction.
1. Prevention first. First of all, the mushroom farm should be kept away from farms, toilets, garbage dumps, sewage ditch, etc.; secondly, clean up the surroundings of the cultivation place, such as haystacks, dunghills, etc., and clean up as much as possible; third, clean up the mushroom shed. , to make it clean and meet the requirements of cultivation mode, the doors and windows vents and other packaging insect nets, insecticide spray inside the shed thoroughly; Fourth, raw and auxiliary materials should not be entered with insects, in particular pests, mostly Raw materials are brought in; fifthly, when raw materials are cultivated, insecticides should be sprayed on the planting sites for the raw materials. During the bagging sowing operation, insecticides should be sprayed on the material table once every half hour to prevent tapeworms from sowing. Sixth, when the fermentation material is cultivated, phoxim 800 times solution is mixed in the material, 400 kg per ton of material can be mixed, and the surface of the material heap should be sprayed with 1000 times of high-efficiency cypermethrin; During the period of bacteria, with the inspection of miscellaneous items, according to the occurrence of pests in the surrounding environment, spraying once per 3 to 7 days of high efficiency cypermethrin; eighth, in order to protect food safety, during the fruiting period must not be used casually, can be concentrated in the mushrooming interval Medication once, you can To the purpose of prevention.
2. Bacteria control. When it is not found in time or when prevention is not in place, a large number of larvae often occur in the base material. Mushroom farmers are known as “membrane worms”. At this stage, they bite the hyphae and fruit bodies, and the stipe or the cap of the fungus is spongy. The bag turns from white to brown. At this time spraying is of no avail, should be treated according to the mushroom bag mushrooming situation, if only a tidal mushroom, biological efficiency of 50% or less, can be completely destroyed in order to continue mushrooming. The method is to use aluminum sulphide to kill, kill within 6 hours, and then continue with the relevant management; if after two surges, generally do not have to kill the drug, can be directly used as waste for high temperature stuffy, you can kill dead.
3. Mushroom mosquito, mushroom fly prevention and control. In particular, during the fruiting period, the occurrence of pests should be closely observed. Once adults are found, they can be intensively killed. Mushroom mosquitoes are extremely resistant to adult mosquitoes. Even if they are sprayed with clean water and land on the ground, their wings will be incapable of flying after they have been exposed to water. After soiling, they will not move and they will soon die. For this type of larvae, aluminum phosphide must be used to kill.
4. Aphid pest control. After the use of schizomidine drugs, the plastic film shall be covered for about 4 hours after the bacterial bag is sprayed. During the mushrooming period, the drug shall be used after harvesting, and direct spraying on the fruit body shall not be conducted.
5. Collembola control. Reference mushroom mosquito, mushroom fly prevention and control methods.
Finally, to remind the mushroom farmer, in the prevention and control of edible fungus pests, it must be medication during the mushrooming interval, not on the fruiting body directly sprayed to ensure product safety.

Bee Pollen comes from nature, is the bee from the flowers (nectar plants and pollen plants) flowers collected in the pollen grains, and joined the special glandular secretions (nectar and saliva) mixed into an irregular Flat round shape. Bee pollen has a unique natural health care and medical and cosmetic value, is more and more people know, is a high-protein low-fat nutritional health food, known as "all-round nutrition food" "concentrated natural medicine library" "Oral cosmetics" and so on, is the treasure of human natural food.

We provide rape pollen, tea pollen, sunflower pollen and mixed pollen, they are all collected from our professional green beefarm base.

We have applied the certificate of ISO, HACCP and GMP, making sure the quality of bee products.
