The reasons for the use of Hua Lu Hong period: Insect pests 1. The wintering eggs of aphids start to hatch and enter the peak period. 2. The overwintering larvae of the leaf roller moth after its emergence. 3. The adult beetle emerged as a hazard, and prevention and control at this time can reduce the damage of the flowering stage. 4. Hawthorn spider mites, two-spotted spider mites overwintering adults emerged during spawning. 5. The golden moth adult eclosion spawns eggs. 6. The period of occurrence of nymphs in the nymph. 7. Cornell mealybugs overwinter eggs hatching period. At this time, the age of insects that occurred in the pests was neat, there was no overlap of generations, and they were relatively sensitive to pesticides, and the control effect of pesticides was significant. Disease 1. The mycelia of powdery mildew spread in a large number of harmful periods. 2. Mycotic disease pathogens infect the flower, with the stigma into the heart. 3. Rust begins to spread in the orchard and infects the leaves. 4. Black spot disease, red spot disease, fungal pathogen spread infection flower. 5. Alternaria began to infest the new leaves. Precautions for Medication 1. Do not use sloppy medications. Begin to use the drug when the center is exposed, and stop using the drug when the inflorescence is completely separated. This will prevent damage to the bud and affect pollination. 2. The product quality must pass the product, the product has poor solubility, and it is easy to precipitate; the purity of product components is not enough, impurities are too much; or other quality problems of the product are likely to lead to unsatisfactory pest control effect, and even some products with poor safety will hurt To the bud. 3. The dosage of the product should be accurate, and it is not allowed to increase or reduce the use of the product arbitrarily so as not to affect the safety and control effect. 4. Must be twice diluted, after the second dilution of the liquid more uniform, more clear, pest control effect is also better. 5. The prepared liquid medicine can not be placed for a long time. In the event of adverse weather such as rain, liquid medicines that have been placed for too long can no longer be used for spraying. 6. Select sunny weather, dry after the morning dew, or spray after 4 pm to avoid spraying when exposed to direct sunlight; avoid spraying in strong winds. 7. The droplets must be fine, and no column of water can shower the fruit trees. Water sprays are prone to phytotoxicity and do not exert their efficacy.
