2-Naphthoxyacetic acid (bnoa) is a naphthalene plant growth regulator with auxin biological activity

Naphthoxyacetic acid (bnoa) is a naphthalene plant growth regulator with auxin biological activity, which is absorbed by leaves and roots. It can promote fruit setting, stimulate fruit expansion, and overcome hollow fruit; When used together with rooting agent, it can also promote plant rooting. Use: it is used as plant growth stimulant to improve the fruit setting rate and regulate the growth of pineapple, strawberry and tomato. Naphthoxyacetic acid can be used on grapes, pineapples, strawberries, tomatoes, peppers and eggplants to prolong the residence time of fruits on plants. The usage is to spray the flower with a dose of 40 ~ 60mg / L in the early flowering stage. This effect is more obvious when mixed with GA3. When tomato blooms, spray flowers with 25 ~ 30mg / L liquid medicine to promote fruit setting and increase yield. Spraying 50 ~ 100mg / L liquid medicine at the initial flowering stage of tomato can stimulate the expansion of ovary and fast fruit growth.  Naphthoxyacetic  acid is a plant auxin, which can promote plant metabolism and photosynthesis, improve stress resistance, and stimulate crop germination and rooting.

Application technology of naphthoxyacetic acid:

(1) Spray 1% powder spoon on the potato block, and 1000 grams of powder per 100 kg of tuber. As the powder attached to the potato block will affect the commodity value, naphthoxyacetic acid can be sprinkled on the paper strip and mixed with the cellared potato. 10 g naphthoxyacetic acid can be used for every 100 kg of tuber. It can be stored for 1 year at the best storage temperature of 10 ℃. Before sowing the next year, take out the potato and put it in a dark and ventilated place. After naphthoxyacetic acid volatilizes, it can be used as seed potato or edible.

(2) Weigh 150g of 98% naphthoxyacetic acid, dissolve it in 300g acetone or alcohol (the drugs used should be prepared now), slowly mix it into 10 ~ 12.5kg powdered fine soil prepared in advance, mix it well, and then put it into a pocket sewn with gauze or linen. Sprinkle the prepared liquid medicine evenly on 5000 kg potato tubers. The bag containing the medicine powder can be tied at one end of the bamboo rod and shaken constantly, and the medicine powder can be evenly sprinkled on the potato block. After the potatoes are packed (baskets), they shall be covered with a layer of paper or linen.
