Termite control in orchards is a headache for many fruit farmers. Both old and new orchards have occurred, especially in newly reclaimed orchards in mountainous areas. Termites are different from black ants. Black ants move on the trunk of the ground and nest in trees, while termites move and nest underground. If you don't pay attention to observation, it is difficult to find it on the ground, and you can only find it by pulling open the base of the fruit tree with your hands. It is understood that the seriously damaged fruit tree is longan. The seedlings harmed by termites have yellow leaves and weak growth potential, and the branches and leaves of severely damaged seedlings wither, or even the whole plant dies.

Termite control methods in Guangzhou and Shenzhen;

1. The biological control is mainly to raise chickens in orchards. Chickens are very sensitive to termites and love to eat termites. Eating termites with chickens can kill two birds with one stone.

2. When planting fruit seedlings by soaking the roots with medicinal mud, add 300 ~ 400 times of 75% phoxim to the soil and mix with medicinal mud, and soak the roots for 3 ~ 5ml.

4. The method of root irrigation with liquid medicine uses 90% trichlorfon crystal 1kg, 500kg of water, 2.5kg for each plant, or diluted to 600,800 times with camphor oil, and sprayed 250mL on the occurrence part.

5. Pro-drug bait trapping and killing method: 25 ~ 30g mirex is used every 667m2, fried rice bran 15t, appropriate amount of rice soup is added and mixed evenly. Apply 65,438+000 ~ 65,438+050g to each plant and apply it to rhizosphere soil.

6. Trapping and killing method of cassava stalks: Set 10 ~ 20 points in the orchard, pile 3 1g cassava stalks at each point, cover them with sugarcane leaves or rice stalks, and seal them into honeycombs with mud after being wetted.
