After the high temperature shack in summer, the pests in the shed are basically eliminated, but many pests will still appear in the shed, especially pests such as thrips. What is the reason for this? In fact, most of these pests are re-transmitted from the outside of. Before planting vegetables, the shed must be well isolated to avoid the spread of diseases and insect pests by personnel and seedlings.
Laying anti-grass cloth around the indoor and outdoor sheds, and setting up tight insect-proof nets at the vents is an important means to prevent the spread of insects indoors and outdoors.
People enter and exit the disinfection shed. The shed is cleaned through the shack, but there are still a large number of disease and insects outside the shed, especially the stalks and other piles accumulated around the shed after pulling out the garden, resulting in a large number of bacteria and nematodes around the shed. The daily entry and exit of personnel is also an important way to cause the spread of pests. It can be sprayed with more than 2 meters of lime powder at the door of the shed, or change shoes in and out, which can play a certain role in disinfection and prevent pests from spreading with people.
A lot of vegetable farmers have done a good job of inspecting seedlings. According to reports, there are many thrips in the shed when the seedlings are planted for more than ten days. However, the shed and the insect net are good. Why are there so many bugs? . If you want the seedlings to grow well, you must first make sure that the seedlings are robust. Carefully check the seedling growth points, leaves, stalks, roots and other parts to ensure that they are comprehensive and detailed. Disinfect the seedlings before planting in the shed. Before seedlings are planted, they can be treated with Bacillus subtilis, Trichoderma harzianum, and Bacillus cereus to eliminate potential hazards such as germs and nematodes.
