After fruit setting, bacterial perforation disease and fungal perforation disease, scab disease and heartworm, peach borer, scale insect and longhorn beetle larvae should also be prevented and controlled. In addition, high potassium water-soluble fertilizer + biological regulation function water-soluble fertilizer in Mumei soil was applied at the melon expansion stage, and potassium dihydrogen phosphate was sprayed on the leaf + Aomeijia chelated calcium + Stekop to promote the expansion and coloring of peach fruits and improve the quality and taste.

Commonly used common agents such as acetamiprid and pyrethroid agents are used in combination. Or it is used in a single or compound combination of pyrethamide, flubelluron, etc., with pymetrozine, dimethoxamin, furidinamide, etc.

What pesticides do yellow peaches need to be injected after fruit set, and what should I pay attention to?

There are two aspects to improve the use of fertilizer, the first is the type of fertilizer, and the second is the method of fertilization. First of all, let's take a look at the types of fertilizers, generally based on farmhouse fertilizers, which will use urea to promote growth, then boron fertilizer and potassium fertilizer for fruit preservation, and finally auxiliary use of some phosphate fertilizers, compound fertilizers and nitrogen fertilizers. The fertilization method is divided into three stages, urea at the seedling stage, phosphorus fertilizer for adult fruit trees, and potassium fertilizer for senescent fruit trees.

The fertilization of adult fruit trees is the most critical of Acacia, it is divided into three steps, the first is the leaf development period, the use of urea and compound fertilizer or farmhouse fertilizer watering, the second is the flowering period, the use of potassium fertilizer and boron fertilizer for spraying, used to promote flowering and fruit preservation, improve the fruit setting rate, the third is after harvesting, the use of farmhouse fertilizer accumulation, for next year's high yield preparation.

When the peach tree is just hung with peaches, pesticides are used to control aphids.

Peach trees enter the young fruit stage after flowering, and the pests and diseases that often occur on peach trees at this time are mainly aphids. The aphids that harm peach trees mainly include peach aphid, peach powder aphid and peach aphid. Peach aphids begin to hatch at the budding to flowering stage of peach trees, and the first hatching nymphs harm peach buds and flowers; With the rapid growth of new shoots, it turns into a leaf damage.

The prevention and control of peach tree aphids advocates early prevention and control, which is carried out at the early stage of damage to the leaves and buds of peach trees. Once the leaf roll is caused, the difficulty of control increases, and the cost of control increases. Therefore, before the peach tree blooms, it is necessary to spray a pesticide to control aphids, and the garden pieces that are not controlled before flowering should be prevented and controlled in time after flowering, and the agent can be selected 70% imidacloprid water dispersible granules 3000-4000 times or 10% acetamiprid 2000-3000 times.

Spray pesticides evenly and thoughtfully, and if necessary, spray again after 7-10 days.

Plant growth regulators, such as abscisic acid, will be known if you ask in a pesticide retail store.

May I ask the teacher, why do peach trees bloom and bear fruit normally, why do large and small fruits appear? But the small fruit is falling away?

Mainly for the prevention and control of pear heartworm, peach aphid and scab, perforation and anthracnose, avermectin plus imidacloprid plus difenoconazole, bacterial perforation needs to add streptomycin, in addition to calcium fertilizer, to prevent cracking fruit and rotten tips, please adopt, thank you!
