Ground tigers are a common underground pest. According to their different types, they can be divided into three types: small tigers, earth tigers and yellow tigers. The tigers seriously affect the normal growth of crops. What are the methods for controlling tigers? Let's take a look at it with Xiaobian.
First, agricultural control: water and drought rotation, ploughing the land, sowing or harvesting artificial insects to reduce the number of insects in the host field.
Second, chemical control
1. Before ploughing, use 250% of 50% phoxim EC and 10-15 kg of moist fine soil per acre and mix it to the ground, then turn it into the soil.
2. When planting, mix with 75% phoxim emulsifiable concentrate 500 times.
3, in the mid-term discovery of larval damage can be used 50% phoxim EC 250 ml, poured with water. 500 kg per acre of liquid medicine, or 2 kg of 3% carbofuran granules mixed with fine soil 25-50 kg, cultivating soil along the ridge.
4. In the early stage of pod formation, it can be used to fill the pier with zinc sulphur phosphate 1000 times or with 812 granules.
5, can be equipped with trichlorfon poison bait in the evening when sprinkled in the field to lure.
Third, biological control
(1) trapping adult insects to kill adult insects with black light; or using sweet and sour wine to trap adult insects (6 brown sugar: 3 parts of vinegar: 1 part of white wine, add a small amount of stomach poison, plus appropriate amount of water).
(2) Protection and utilization of natural enemies such as insectivorous birds, walking insects, cockroaches, cockroaches, apids, parasitic flies and fungi.
(3) Elimination of weedy weeds is the feeding material of the tiger's spawning place and young larvae, and removes weeds and sundries, which can greatly reduce the density of the insects.
Today's introduction to the prevention and control of tigers is here. To get more knowledge about pesticides , please pay attention to China's pesticide network.
