Dear friends, everyone, the Century Pesticide Network Xiaobian has come to give you a general approach to the prevention and control of plant diseases and insect pests. Doing a good job in the prevention and control of pests and diseases is a very important part of the planting process and is of great significance for improving production. Let's take a look at it with Xiaobian!
cabbage caterpillar
Cabbage worm: mainly damages cabbage, rape and so on.
Control method:
(1) Agricultural methods: Care should be taken to clean up the pastures to eradicate weeds and deepen the land to eliminate wintering. The recovered leaves of the residual plants should be removed in time to reduce the number of cabbage caterpillars.
(2) Cultivation of no seedlings. Use insect nets to prevent seedlings from laying eggs on the seedlings.
(3) Chemical control. The agent can be selected by using 2.5% spinosyn rubber suspension 1000 times solution, or 5% flubendialdehyde emulsifiable oil 2000-2500 times solution, or 5% fluoropyridine urea emulsifier 2000-2500 times solution, Bt500-1000 times solution spray. It is necessary to spray control at the peak of the first and second instar larvae.
Plutella
Plutella xylostella: mainly damage Chinese cabbage, radish, cabbage, etc., followed by green vegetables, Chinese cabbage and so on.
Control method:
(1) Agricultural methods. After harvesting vegetables, it is necessary to clean the leaves of the field in time, and plow the vegetable fields in time to reduce the food source of the first peak of the insect source and reduce the density of the insects. The method of changing irrigation is sprinkler irrigation.
(2) Physical control. A frequency-vibration insecticidal lamp is installed in the vegetable field, and the light is used to trap the adult insect.
(3) Chemical control. The agent can be selected by using 2.5% spinosyn rubber suspension 1000 times solution, or 5% flubendialdehyde emulsifiable oil 2000-2500 times solution, or 5% fluoropyridine urea emulsifier 2000-2500 times solution, Bt500-1000 times solution spray. It is necessary to spray control at the peak of the first and second instar larvae. Initiate the mixing and use of the drug to delay or hinder the resistance of the pest.
