Naphthalene acetamide (trade name: NAD, other names: Amid-ThimW) is a naphthalene plant growth regulator.
The role of naphthalene acetamide
Naphthalene acetamide can be absorbed through the stems and leaves of plants, and its conductivity is slow, which can cause the formation of peduncle abscission, so as to be used as a fruit thinning agent for apples and pears, and also has the effect of promoting rooting.
Uses of Naphthalene Acetamide
Naphthalene acetamide is a good fruit thinning agent for apples and pears.
(1) Apple is sprayed on the whole plant at 25～50mg/L concentration 2～2.5 weeks after full bloom (when the petals fall off).
(2) Pear with the concentration of 25～50mg/L, spray the whole plant when the petals fall to 5～7d behind the petals.
(3) Naphthaleneacetamide mixed with related rooting substances is a broad-spectrum rooting agent for promoting apples, pears, peaches, grapes and ornamental crops.
The formula used is as follows: 1) Naphthaleneacetamide 0.018% + Naphthalene acetic acid 0.002% + Thiourea 0.093% 2) Naphthalene acetamide is mixed with indole butyric acid, naphthalene acetic acid and fumet.
Precautions while using naphthalene acetamide
(1) When used as a fruit thinning agent, the medication period should be strictly controlled, and the fruit thinning effect is related to temperature, so it is necessary to obtain demonstration experience first and then gradually promote it.
(2) This variety is widely used as an important component of rooting agent in the United States and Europe.
(3) Do not get the liquid into the eyes, and wear protective glasses during operation.
