Control methods of common diseases and insect pests in pineapple

Pineapple, commonly known as pineapple, is a hot tropical fruit in summer. It has high yield, stable market price and remarkable economic benefits. Attract a lot of people to plant, but with the increase of planting area and density, accompanied by a variety of diseases and insect pests, affecting the yield and quality. So what are the diseases and insect pests when pineapple is planted? How to prevent and cure it? Let's take a look at the detailed introduction of the pro-agricultural network.

1. Fusarium wilt

Fusarium wilt mainly harms the leaves, after the disease, the leaves begin to soften and sag, and the leaf color changes from green to red. When the disease is serious, the base of the plant decays, resulting in plant death. The disease is mostly caused by pink scale insects.

Control methods: select the seedlings with strong growth and no disease during reproduction, disinfect the seedlings and soil before planting, and pay attention to the control of pink scale insects, soak the head with 500 times dimethoate solution when planting, and then plant after drying. When diseases are found, spray 500 times dimethoate solution in time. If it is a seriously diseased plant, pull it out of the garden in time so as not to spread to other plants.

2. Black rot

Black rot is a disease caused by fungi. the spores of the fungus overwintered early on the soil or residual plants, causing damage to fruits, mainly on ripe fruits, especially in the stage of storage and transportation. During the onset of the disease, the external characteristics are usually not obvious, when the disease occurs, the fruit appears water-stained disease spots, with the disease spreading to dark brown irregular disease spots, until the whole fruit. When the fruit is cut open, it will be found that the inner edge of the fruit appears water-stained soft rot, while the central part is dark brown, and the serious disease is that the internal tissue is rotten and black.

Prevention and control methods: after fruit ripening, harvest should pay attention to time and methods, do not top and harvest in rainy days, lest germs invade; handle gently during harvest, prevent sun exposure after harvest, and disinfect harvesting tools, or drop disinfectant at fruit cracks.

3. Heart rot

Heart rot is mainly harmful to the seedling stage, which is caused by heap fever or excessive stagnant water, the seedlings wither at the onset of the disease, and the seedlings die in the later stage.

Prevention and control methods: to avoid long-term stacking of seedlings, especially in transportation and planting, the heat collection and heat dissipation are not good under high temperature environment, resulting in seedling damage; in addition, watering should be appropriate when planting, so as not to cause stagnant water and make them get sick. Pay attention to drainage measures in overcast and rainy weather.

4. Insect pests

Pineapple pests are mainly crickets, grubs, unicorn immortals, pink scale, pineapple spider mites, they absorb juice or eat fruits and roots, affecting the yield and quality of pineapple, and in serious cases lead to no harvest.

Control methods: agricultural control and chemical control can be used, pay attention to clear the cause when planting, reduce the source of insects, and find that insect pests can be reduced and sprayed to control.

The above are the common pineapple pest control methods brought by the pro-agricultural network, I hope it can help you, more agricultural knowledge, please pay attention to the pro-agricultural network.
