Application technology

Ⅰ.Use alone to control the nutritional growth of crops

1.Food crops: seeds can be soaked, leaf spraying and other methods

(1)Rice seedling age 5-6 leaf stage, use 20% paclobutrazol 150ml and water 100kg spray per mu to improve seedling quality, dwarfing and strengthening plants.

(2)From tiller stage to joint stage, using 20%-40ml of paclobutrazol and 30kg of water spray per mu can promote effective tillering, short and stout plants and enhance lodging resistance.

2.Cash crops: seeds can be soaked, foliar spraying and other methods

(1)Peanuts are generally 25-30 days after the beginning of flow ering, the use of 20% paclobutrazol 30ml and 30kg water spray per mu can inhibit the growth of nutrients, so that more photosynthetic products are transported to the pod, reduce the number of ruffs, increase the number of pods, fruit weight, kernel weight and yield.

(2)In the 3-leaf stage of the seedbed, the use of 20% paclobutrazol 20-40ml per mu and 30kg spray with water can cultivate short and strong seedlings, avoid the emergence of “tall seedling”, “curved root seedling” and “yellow weak seedling”, and the transplanting has less broken, fast survival and strong cold resistance.

(3)At the initial flowering stage of soybean, using 20% paclobutrazol 30-45ml and 45kg water spray per mu can effectively control vegetative growth, promote reproductive growth, and make more photosynthetic products flow to the kernel. The stem internode of the plant was shortened and strong, and the number of pods was increased.

3.Fruit trees: soil application, leaf spraying, trunk coating and other methods

(1)Apple, pear, peach:

Soil application before spring sprouting or autumn, 4-5 years of fruit trees use 20% paclobutrazol 5-7ml/m²; 6-7 years of fruit trees use 20% paclobutrazol 8-10ml/m², adult trees 15-20ml/m². Mix dobulozole with water or soil and put it into the ditch, cover it with soil and water it. The validity period is 2 years.Foliar spraying, when the new shoots grow to 10-15cm, use 700-900 times the solution of 20% paclobutrazol evenly spray, and then spray once every 10 days, a total of 3 times, can inhibit the growth of new shoots, promote the formation of flower buds, and improve the fruit setting rate.

(2)In the early stage of budding, the grapes were sprayed with 20% paclobutrazol 800-1200 times liquid leaf surface, once every 10 days, a total of 3 Secondly, it can inhibit the pumping of stolons and increase the yield.

(3)In early May, each plant of mango was mixed 15-20ml with 15-20kg of water, which could control the growth of new shoots and improve the heading rate.

(4)Lychee and longan were sprayed with 500 to 700 times liquid of 20% paclobutrazol suspension before and after pulling out the winter tips, which had the effect of increasing the flowering rate and fruit setting rate and reducing fruit dropping.

(5)When the spring shoots were extracted 2-3cm, spraying the stems and leaves with 20% paclobutrazol 200 times liquid could inhibit the spring shoots, reduce the nutrient consumption and increase the fruit setting rate. In the early stage of autumn shoot germination, using 20% paclobutrazol 400 times liquid spray can inhibit the elongation of autumn shoot, promote flower bud differentiation and increase yield.

Ⅱ. Mixed with pesticides

It can be mixed with most insecticides and fungicides to save time and labor, which can kill insects, sterilization, and effectively control crops long. Recommended dosage for general field crops (except cotton) : 30ml/ mu.

Ⅲ. Compound with foliar fertilizer

Paclobutrazol suspension can be mixed with leaf fertilizer to improve fertilizer efficiency. Recommended dosage for general foliar spraying: 30ml/ mu.

Ⅳ. mixed with flushing fertilizer, water-soluble fertilizer, drip irrigation fertilizer

It can shorten the plant and improve the absorption and utilization of the required nutrients of the crop, and it is generally recommended that the amount of fertilizer used per mu is 20-40ml.
