Core Tip: After the apple is dropped from flowering to bagging, as the temperature rises, a variety of pests and diseases have begun to occur or some diseases and insect pests will occur. Grasping this opportunity to prevent and control pests and diseases will lower the base number of pests and diseases, which can be applied to apples. The high yield and quality of the products and the improvement of the inner quality of the apple have an extremely important role.
Three key medications
The first medication, the optional agent: fruit Long 12000 times or applied 10000 times added insect clear fourth 8000 times plus sword power 3000 times or beautiful 1000 to 1200 times Gaglisky 600 times or heavy calcium 2000~2500 times soft Water pass 4000 times.
The second medication: This medication is the critical period for combating cottonworms. The pesticide is the preferred choice of Anminol. Optional agents: An Minle 1000 times plus insect clear four times 8000 times plus 3,000 times the force of the sword or Li Lai 1000 to 1200 times the Galeas 600 times or 2000 to 2500 times the number of soft water plus 4000 times.
The third medication: it is the last medication before bagging, which is the key to prevent apple bagging problems. Two types of fungicides are generally used, protective agents and therapeutic agents. Within three days after treatment, good quality fruit bags are selected for bagging. Optional agents: 10,000 times the introduction of insect clear Qing 8000 times, plus 3,000 times the sword power or Li Lai 1000 ~ 1200 times higher 600 times Gaglisky 600 times or 2000 ~ 2500 times the weight of soft water through 4,000 times.
Pay attention to nutritional supplements
Calcium can not only increase the ability of new roots of fruit trees, increase tree vigor, but also promote the thickening of apple cell walls, avoid cracking of apples, and enhance the resistance of fruit trees to the external environmental environment, and prevent shortages such as spot and spot diseases. Calcium physiological diseases occur.
There are two crucial periods for the absorption of calcium by apple trees. The first is the young fruit period after flowering until the bagging, and the second is the highest utilization rate after bagging after bagging. Therefore, it is important to pay attention to calcium supplements after the flowering and before the bagging. Every time you spray, you should add some calcium and you should add calcium at least 3 times a year. Calcium is the preferred organic calcium and calcium chelate.
The apple should be nutritionally supplemented before bagging, usually in early June. Nitrogen and potassium fertilizers are the main factors. Nitrogen fertilizer can promote fruit enlargement, and potassium fertilizer can promote the conversion of mixed buds into flower buds. According to the situation of fertilization for many years, the high-nitrogen, high-potassium and low-phosphorus compound fertilizers have a good effect in this period. At the same time, fertilizers should be applied on the ground. Amino acids can be used for drying, sprinkling, and spraying leaves. They can be used for the purpose of quickly supplementing organic nutrients and keeping trees vigorous.
Prevention of Mycotic Warts and Mycotic Heart Diseases
Once the apple wraps do not pay attention to prevention and control, it will cause serious damage to the fruit, leaves, branches and roots, resulting in decline in yield and quality tree vigor, affecting the life of the apple tree. Under normal circumstances, the most favorable time is in mid-May of each year, that is, the time after the apple is dropped to the second time before bagging. If the apple seedlings in the garden are relatively harmless, the second pesticide insecticide after the flowering and then bagging is preferred to have strong penetrating agents such as Anminole and Le Siben, and it is also very effective in preventing and controlling leaf roller moth and scale insects. effect.
Usually, when farmers control fungal disease, they will choose a good quality bactericide to spray once every time in floral red, early flower, full flower and falling flower. However, such a cost is too high, the phytotoxicity is prone to occur during flowering, and the amount of pesticide residues in fruits is large because of the excessive number of applications. The feasible methods of prevention and control are as follows: First, attach importance to the Qingyuan Garden, select good-quality fungicides, and evenly and meticulously spray the fruit trees to reduce the base number of pathogenic bacteria that cause fungal heart disease. The second is to use a bactericide alone according to the weather when it is 80%. If the temperature is stable, use protective agent bactericide; if the temperature is unstable choose therapeutic bactericide. The third is to pay attention to use two kinds of eradication fungicide when applying medicine before bagging, such as multi-antimycin plus Lizhi, or agricultural resistance 120 plus Lizhi.

Function:
1.Monobenzone is a compound used as a topical drug for medical depigmentation.
2.The topical application of monobenzone powder in animals decreases the excretion of melanin from melanocytes. The same action is thought to be responsible for the depigmenting effect of the drug in humans.
3.Monobenzone may cause destruction of melanocytes and permanent depigmentation.
4.The histology of the skin after depigmentation with topical monobenzone powder is the same as that seen in vitiligo.
5.The epidermis is normal except for the absence of identifiable melanocytes.
