Prohexadione calcium

Physical and chemical properties:

light Yellow powder

Functions:

Prohexadione calcium can shorten the stem elongation of many plants, and it acts through the treatment of the pages, and it has the potential to replace the pesticides with no residual toxicity and no pollution to the environment, compared with the currently widely used triazoles. The main role of Prohexadione calcium is: to promote fertility, reduce lodging, promote lateral bud growth and hairy root, so that the ability of stem and leaf and drought resistance, reduce Herbicide the key to improve plant resistance to Inverse.
It can shorten the internode, improve the lodging resistance, control the horizontal and vertical growth, can make crops have a certain role in production. Mainly for barley, rice, wheat and turf growth regulation, with significant lodging and dwarfing performance. The effect of anti - volatilization of rice was obvious, the growth inhibition of turfgrass was significant, the effect of low dose was obvious, and even at high dosage,

Method of use:

Rice: Prohexadione calcium is applied at the end of the tillering stage (7-10 days before jointing) when the rice is transplanted to the paddy field. The effective amount is 10-30g / ha, which has the effect of reducing internode length on the one hand, and dwarfing plant base Height, increase the mechanical strength, improve the lodging resistance; on the other hand, reduce the shriveled grain rate, increase the number of grains, thereby increasing the yield per unit area is an important way to achieve high yield of rice Prohexadione calcium to resolve the lodging resistance of rice And high-yield contradictions, to ensure a certain plant height and planting density of rice under the premise of biological characteristics to improve the lodging resistance and growth capacity of rice is 5-15% increase per mu of rice, so as to achieve the perfect cultivation control The purpose of wheat, barley and other grasses crops also have the same effect.

Peanut: field test results show that the effective ingredient per acre Prohexadione calcium 5 grams can significantly increase the thickness of peanut leaf and chlorophyll content, and promote leaf photosynthesis; improve leaf SOD \ POD and CAT and other protective enzyme activity and soluble protein content, Vitality, increase the number of fruit per plant and fruit weight, increase the economic coefficient and pod yield significantly.

Fruit trees: apples, pears, hawthorn, cherries, plums, etc., with 125-250ppm concentration within 10 days after fertilization, can significantly inhibit leaf and shoot growth, improve fruit yield, improve fruit quality and yield , While the fire blight and other diseases caused by bacteria and fungi also has a very good preventive effect.

Cotton: In the middle period of cotton growth, it is effective to inhibit the growth of leaves and shoots, reduce the height of plants, optimize the effect of ventilation and light transmission, increase the yield and improve the quality.

Grape: After grape Xiehua, the use of 250ppm concentration of foliar fertilization, can effectively inhibit the growth of grapes, increase grape juice pigment and phenolic content, improve grape quality, but also has a certain yield.

Cautions:

Prohexadione calcium is a high activity plant growth regulator, for the poor fertility, growth is not busy with caution.
2. In strict accordance with the instructions medication, so as not to cause the key;
3. Application should be before 10 am, after 4 pm to leaf wetting without dropping is appropriate, so you can increase the absorption time of the leaves, they will not waste;
4. Long-term contact with the skin harmful, after spraying should be promptly cleaned; if misuse taking cause poisoning, should be sent to the hospital remedy.
5. Can not be mixed with alkaline substances
