In recent years, many farmers have used hormones such as auxin for the control of tomatoes. However, due to improper use of auxin, it often causes small fruit, cracked fruit, and green top. To this end, it is recommended that tomato chemical control should be based on nutritional regulation, and care should be taken to prevent the following.

1. "Small fruit disease": Because the farmers use the Zhuangsu (or Dwarf King) in the tomato seedling stage, the dose is large and the time is late (usually in the "high seedlings"). Although the plant height is controlled, it is also suppressed. Ear development. At this stage, the “rooting and seedling method†should be adopted. The specific method is: use 500~800 times Gaomei applied organic humic acid active liquid fertilizer to fill the roots, use 100~150 grams of liquid per plant, and spray Wanchun plant growth agent plus carbendazim or green hengyi No.1 to promote root development. And improve disease resistance.
2. "Splinter Fruit Disease": Using the chemical control, it can thicken the peel and make the flesh expand rapidly, thus forming "split fruit disease". Prevention of this disease should increase boron, calcium, and cooling. Specifically, in the tomato flowering period, spray 300-500 times of humic acid boron calcium or 300-500 times of high-beauty application, and use the small fertilizer to wash the root potassium.
3. "Green Top". Because some farmers have increased the fertilizer and water temperature management, the fruit development is too fast, coupled with the uneven use of hormone spraying, resulting in uneven development of various parts of the fruit, forming "green top disease." The root cooling method should be adopted for control. Specifically, when the second and third panicles grow out of the tomato, the bio-organic fertilizer plus potassium sulfate compound fertilizer is applied to the ditch or the hole to promote the growth of the secondary roots, and the ability to absorb water and absorb water is cultivated, which lays a good foundation for the late growth stage.
