Scope of application
It is suitable for cereal crops to increase tillering, ear formation rate and 1000-grain weight. Cotton reduces the shedding of buds and bolls, increases the weight gain of peaches and improves the quality. Fruit trees promote flowering, prevent fruit
falling, accelerate ripening and increase production. Melon and fruit vegetables prevent falling flowers and form small seed fruits. Promoting rooting of cutting branches, etc.


1. NAA 98%tc is a widely used plant growth regulator that especially effective when plant absorbs nutrition via root, stem or leaf.
2. NAA 98%tc is used in agriculture, forestry, vegetable, flower, fruit, etc.

Use method

1. Soak rice seedlings with 10mg/kg of liquid medicine for 6 hours, and the seedlings will turn green quickly and have thick stems
after transplanting.

prevent the buds and bolls from falling off.
3. Sweet potato was soaked in 10mg/kg liquid medicine at the lower part of seedling (3 cm) for 6 hours and then planted to

7. After pineapple nutrients have matured, 30 ml of naphthylacetic acid solution with a concentration of 5-10 ppm is injected into the nucellus of each plant, which can directly change the vegetative growth to reproductive growth, so that pineapple buds will appear 1-2 years in advance and the yield per unit area will be greatly increased.
8. Naphthylacetic acid 200-300 ppm is used for fruit thinning of citrus fruits, which has fruit thinning effect on Satsuma mandarin 10-30 days after flowering, but it has no fruit thinning effect if the fruit diameter is over 20mm more than 50 days after flowering.
9. 1 gram of naphthylacetic acid and 100 grams of water are mixed into a solution to promote the healing of the marriage joint,then waste paper is cut into strips and immersed into the solution, and dried in the shade to obtain hormone paper. Using hormone paper to bind up grafting parts of fruit trees is beneficial to callus formation. Compared with the unbinding ones, it can survive 3-5 days earlier.
