Coffee branch borer in the garden is a common phenomenon nowadays, mainly causing damage on newly planted trees. The branches that are attacked by weevils often have to be cut off, the tree takes a long time to recover, greatly affecting yield, resistance and slow growth. So how to get rid of the root borer phenomenon? Bio Sacotec will guide you how to effectively identify and prevent weevils through the content below!

Coffee branches that grow green are good for fruit

HARMFUL EYES ON COFFEE PLANTS

Causes and conditions of occurrence

The scientific name of the branch borer is Xyleborus morstatti Hagedorn. Female morphology is dark brown, membranous, 1.6 – 2.0 mm long. Males are brown, smaller than females and only 1.0 mm long, without membranous wings, so they cannot fly. On the body there are many soft brown hairs.

The branch borer causes heavy damage on the gardens at the basic construction stage, mainly on young, newly emerging branches. Adult weevils make a small hole under the twigs or on the side of the overhanging shoots to form a hollow nest and burrow inside to lay eggs, drying out the branches. died. For branches with a diameter of > 9 mm when damaged by weevils, the branches will not dry out, but will later be broken due to fruit bearing.

The activity of the branch borer usually appears in the dry season months, then gradually decreases until the next year’s rainy season. They still live on avocado, cocoa, mango, large-seeded yellow flowers…

Weevils attack strongly on young coffee trees, newly developed, young branches

Symptoms of weevils on coffee

Coffee branches attacked by weevils usually show symptoms with 3 stages:

• Stage 1: First, the triangular scales at the nodes of the coffee branch turn black, a few pairs of leaves near the hole move towards the tips of the fallen branches.
• Stage 2: The branches with borer weevils have wilted, only a few pairs of leaves are left at the tips of the branches.
• Stage 3: The branches are dead and dry.

The dry season is the time when weevils thrive and thrive

How to treat coffee branch borers

• Check the garden regularly, especially at the beginning of the dry season for basic plants to detect early weevils in order to cut, destroy, and prevent their growth.
• When cleaning, it is necessary to cut off branches affected by borer weevils in stages 1 and 2 for high prevention efficiency. Because in the third stage, only 20% of the branches still have weevils inside the hole. Cut the branches at a position at least 8 cm from the hole in the coffee tree to collect all the nests.
• When detecting weevils attacking coffee, people use 500ml of SCT 08 mixed with 400-500l of clean water to spray evenly on the disease spots on the tree to prevent their growth. Then, about 5-7 days, spray the second time to promote the full effect of the insecticide.

COFFEE FACE ON COFFEE PLANTS

Causes and conditions of disease occurrence

Cause: The scientific name of the fruit borer is Stephanoderes hampei Ferriere, also known as Hypothenemus hampei Ferrari. The adult beetle is a small, dark brown or glossy black, winged or wingless beetle about the size of a sesame seed.

Harm: Infested coffee beans often have a small round hole next to the knob or in the middle of the knob. When the fruit is split, it can be seen that inside the seed, there may be eggs, white larvae and black adult weevils. Depending on the severity of the damage of the fruit borer, the damaged part of the kernel is black, the kernel is partially or completely voided.

People must identify the characteristics of weevils that attack on coffee berries to take quick measures

Fruit borers are considered dangerous pests because they not only cause damage in the field but also damage during storage.

Fruit borers can survive year round on coffee gardens. Weevils usually appear when coffee cherries are in the old green stage, ripe fruit, can grow in the dried fruit left on the tree after harvesting or the dried fruit fall on the ground. Weevils can destroy both dried and green coffee beans during the storage period if they are not dried and the moisture content of the beans is still high (≥ 13%).

Applying the right prevention technique, weevils are no longer harmful on coffee trees

• Dry fruits and seeds before storing at less than 13% humidity.
• In areas that are heavily damaged by fruit borers for many years, chemicals can be used to spray the whole garden.
