Application time For Wangchang peach tree, it can be applied to the soil in the spring flower bud expansion period, and early exertion of medicinal effects can be used to control the growth of new shoots and increase the fruit setting rate. For peach trees growing in the golden age, shoots are vigorously grown after shoots (about 20 cm in length) to control the occurrence and growth of their secondary branches. For peaches with moderately growing middlings, they can be sprayed with 500-1000 mg/kg paclobutrazol on trees in August to increase flower bud quality. When applying pesticides, it should be noted that 1-2-year-old saplings and weakly growing trees should not be applied. Application amount The amount of application depends on factors such as the age of the tree, the strength of the tree, the size of the canopy, and the type of the species. Wangshu and big trees should be applied in multiple ways, but vice versa, yellow mellow peaches of late varieties such as gold and yellow husks should generally be used 10% to 20% less than those of southern honeysuckle and Okubo. For the first application, 0.5 to 1 g (approx. 15% paclobutrazol WP product volume) of the canopy projection per square meter was applied. Soil application has a significant effect for 3 years, with the most significant effect in the first year and decreasing thereafter. How to apply pesticides in the second year should be determined according to the growth and development status of peach trees: After the first year of application, the middle and long fruiting branches formed by peaches account for about 30% of the total branch weight, and a small amount of secondary branches are pumped. It shows that the application amount is appropriate and that the application amount in the next year can be about 50% of the application amount in the previous year; if the percentage of medium and long fruit branches that are drawn on the peach tree is large, more and more are drawn. The second branch indicated that the application in the previous year was less, and the application amount in the next year should be more than 60% of the application amount in the previous year; if the result of the pumping, the branches were mostly short fruit branches and bouquet-like fruit branches. Long fruit branches are weak and drooping, indicating that the application amount is too large and should not be applied or applied less in the next year. If the application amount is too large, the peach tree will be inhibited from growing too much. It is necessary to find it early and spray 50 mg/kg of gibberellin in time to reduce its inhibitory effect. Application method It has been proved by most experts that paclobutrazol has the best effect in soil application. The method is to dig an annular groove with a depth of 10 cm and a width of 30-50 cm inside the outer edge of the canopy projection, diluting the agent with water to 1000-2000 times, and then evenly spraying the prepared solution In the annular groove, the soil is covered with water. During the spraying process, it is necessary to constantly stir and mix the liquid medicine to prevent precipitation, resulting in uneven application and affecting the effect after application. It is also possible to excavate the ring ditch according to the above method, mix the powder with a fine soil, spread it evenly in the ditch, mix it well with mash, and water it after covering the soil. Post-administration management Peach paclobutrazol applied after the formation of flower buds increased, fruit set rate increased, yield increased. Therefore, it is necessary to strengthen soil, fertilizer, and water management to meet the needs of its growth results. When pruning in winter, it is necessary to adjust the amount of flowers, and appropriately increase short and short cuts, and eliminate short and thick fruit branches and fruit-like fruit branches. After fruiting, fruit thinning should be carried out to adjust the amount of results so as to prevent excessive fruits from affecting fruit quality, weakening tree vigor, and accelerating the aging of peach trees.

How to use paclobutrazol to control peach trees
Peach trees grow faster, especially young peach trees, which grow more prosperous. Peach trees, with their high yields and stable yields, must have a good tree shape, which requires manual pruning of peach trees. Relying on labor alone is not only costly, but due to the different levels of technology, it is easy to cause adverse effects on tree vigor. Applying paclobutrazol to peaches can overcome the above disadvantages. Paclobutrazol is a plant growth retardant and broad-spectrum insecticide widely used in fruit trees in recent years. It is a highly effective and low-toxic compound.
