Small coffee cultivation techniques

Control methods: 1 strengthen management, reasonable pruning, appropriate shade. 2 Manually kill adult worms and larvae, and promptly remove the damaged branches and burn them.

2. Coffee Leopard wood moth. Widely distributed, it is one of the common coffee pests that can harm a variety of economic crops. When larvae overwinter in the branches, the larvae often feed upward in the branches to form a 30-60 cm tunnel.

Control methods: 1 Combine pruning with coffee trees and cut off damaged branches to burn them together. 2 Use wire to pry into the worm to stab the larvae. 3 Inject 1 :10 dichlorfon aqueous solution into the hole of the insect, then pour into the hole with drug-impregnated cotton, and then close the hole with mud, so as to poison the larvae of the main coffee.

3. Scale insects: 1 coffee green scale insect. Regardless of adult trees or seedlings can be harmed, branches, leaves, stems, and fruits are the victims. The dry season has been severe. The number of populations has dropped sharply during the rainy season. Ants are often active on the victim tree. Yellow leaves after injury, deformity shrinkage, and often induced the occurrence of a large number of soy, a great impact on coffee photosynthesis and plant growth.

Control methods: use dimethoate or speed culling, kill fluttering spray, spray once every other week, 3 times in a row, the effect is very good. It can also be sprayed with lime sulfur or rosin mixture.

2 coffee root meal. The main damage to the roots, early in the vicinity of the root neck damage, and later spread to the main root, lateral roots, sucking their juice. The worm is transported by ants (the small yellow ants on the stem and the surface of the affected plants often crawl back and forth and pile up fine clay) and coexist with the fungus. In the later stages of the disease, the fungus forms a string of gray-brown tumors in the roots, enveloping the insects, affecting the growth of the roots, and causing black rot and death.

Control methods: At the beginning of the damage, dichlorobenzene powder was sprinkled around the root neck and about 10 cm deep in the soil. After 7 days, the mortality rate reached 92%. In the later stages of damage, the top soil around the roots can be removed, and the depth is about 10 cm. 30 g of paradichlorobenzene is sprinkled, and the cover soil is practical. The mortality rate can reach 100% after 7 days.
