What kind of medicine should be given during the period of banana ear development? Please introduce the tender fruit of banana, which is vulnerable to diseases and insect pests. The main diseases are scab, anthrax and so on, and the insect pests are mainly thrips. Flower thrips have entered the bud to harm the tender fruit after budding, so insecticide control should be sprayed after budding, which is usually sprayed before bagging, mainly to control scab. At present, all banana purchasers are based on the length of fruit fingers, and plant hormones or nutrients can be sprayed on the ear when the buds are broken. The main hormones are 2je 4D, 6-benzylpurine and other nutrients, such as potassium dihydrogen phosphate, urea, phytosin, plant protection 18 and so on. However, the resistance of young fruit is poor, and too high concentration will cause drug damage, so we must be careful to apply it, especially 2mem4murD hormone. The sensitivity of banana fruit in high temperature period is strong, and the concentration should be slightly lower. The best spraying period of banana fruit is within 48 hours after bud breaking, and the fungicide must have good distribution. The atomization effect of the sprayer is good and uniform. When spraying, the amount of spraying on the lower half of the ear should be slightly larger. Since 2mae4Mel D is strictly prohibited in the international market (such as Japan), 6-benzylpurine and gibberellin should be used as the main regulators of fruit index growth. However, when the length of the fruit finger is more than 30 cm, it is more difficult for the fruit finger to grow full, and the growth period is longer, so topdressing and water management should be strengthened during the fruit hanging period.
