The banana leaflets are often harmed by pests such as banana weevil, cymoloides, skipper, Spodoptera litura, nettle, leafhopper, etc. before they grow to buds; banana leaf heart rot, bunchy top, leaf spot, stem Diseases such as rot and yellow swollen diseases. As a result, banana leaves and plants are damaged, causing the banana leaves to be incomplete, yellow, necrotic, and dead. Seriously affect the growth and development of bananas, slow growth, delaying the bud or unable to pull buds and fruit. Therefore, it is necessary to strengthen the prevention and control of diseases and pests in the middle of banana growth to ensure the normal growth of bananas and promote the high yield and quality of bananas. The prevention and control techniques for banana growing season are described below.
1. Weevil: Mainly harms banana pseudostems. For banana gardens that are ineffective for clear gardens, they should remove dead leaves and residual stems in time, excavate old banana heads, burn them centrally, or bury them deeply to eliminate breeding sites. Pay attention to the inspection of the banana plant. If it is found that there are tree gums out of the pseudo-stem, you can spray or sprinkl the pseudostem with 1000 times of farmland or 2000 times of kungfu. Use Miller or Earth Star particles to be placed on the banana head or on the abacus, cover the back of the earth, or place 3 to 6 grams of Milor or Earth Star at the bifurcation of 3 to 4 old leaf sheaths. Once every 20 days, use 2 to 3 times for poisoning.
2. Cross veins, nets: mainly draw leaf juice. To master the initial occurrence, use pesticides such as 1.5% Pole 1500 times or 2.5% Kung Fu 3000 times. Once every 10 days, spray twice.
3. Larvae, Spodoptera litura: mainly harm the leaves. Regularly check the banana plant and promptly remove the insect or egg mass. When the newly hatched larvae are concentrated on the edge of the leaves or on the back of the leaves, they are sprayed with 1.5% Pluronic® 1500x or 10% efficient Xeroxa 2000x.
4. Leafhoppers: The main damage to the leaves, the suction juice, the leaves were gray white, severe leaves dead. Pay attention to the inspection and found that when there is a flaw in the veins on the back of the leaves, it can be sprayed with a 1,000-fold solution of dicofol or a 1,000-fold solution of cesium tetracycline or a 1500-fold solution of acrotic acaricide. Medication alternately used, once every 7 to 10 days, even spray 2 or 3 times.
5. Mosaic heart rot, beam top disease: the main harm to plants. Both diseases are viral diseases, and comprehensive control methods should be adopted for prevention and control, prevention of pathogens, and prevention of infection. Strengthen fertilizer and water management, increase organic fertilizer. When the diseased plant is found in the banana fields, the whole tussock plant should be extirpated together with sucking buds and banana roots. See a single plant for digging, destroy it centrally, and use the insecticides such as Pollock to kill the cross veins and completely eradicate it. Transmission media. At the same time adding 800 times liquid strong gram virus, bactericidal clear and poly-nuclear or multi-nucleic acid and other growth regulator spray, improve plant immunity and promote healthy growth. Severely affected banana orchard rotation.
6. Leaf spot disease: It mainly damages the leaves. In severe cases, the leaves will die from top to bottom. When the old banana leaves were found to have water-stained lesions, or the diseased banana plantations, diseased leaves and dead pseudostems were promptly cut off, and they were burned out of the park. Timely use 25% enemy force to take off 1200 times or 30% love seedling 1500 times liquid or 25% potential gram 2000 times liquid to prevent and cure melanoma, once every 15 to 20 days, once every 2 to 3 times, in case of strong wind After heavy rain, it is necessary to make up the spray in time to protect the wound and the control effect is obvious.
7. Stalk rot, yellow swollen disease: The main hazard is pseudo-stem and petiole. When the disease is severe, the leaves and pseudo-stems become yellow and dead. The diseased plant was found and the dead stem of the diseased banana strain was promptly cut until a healthy pseudostem was visible. After finishing the diseased plants, brush the pseudo stems with Garrinon 500 times solution or thiophanate-methyl 300 times solution mixed with yellow mud and apply once every 10 to 15 days. Apply evenly 2 to 3 times. Then apply Garethon 1000 times or moldin 800 times solution to spray the pseudo-stem and pour the solution from the bifurcation.
