1-Naphthylacetamide (NAD)

1-Naphthylacetamide (NAD) is a plant growth regulator for root promoting and as fruit thinning agent inducing abscission of flower buds.

1-Naphthylacetamide (NAD) is a good fruit thinnning agent. Rooting agent for apples, pears, peaches, grapes and ornamental crops, usually mixed with other rooting agents.

1-Naphthylacetamide can be absorbed through the stems and leaves of plants, and its conductivity is slow. It can cause the formation of peduncle separation layer, which can be used as a fruit thinner for apples and pears, and it can also promote rooting.

If have any problem of technical index or compatibility of NAD, please feel free to contact our team.

1. Fruit thinner  2. Root Growth Promoter


For Fruit Thinner:

  • Apples are sprayed on the whole plant at a concentration of 25-50 mg/L 2 to 2.5 weeks after blooming (when petals fall off).
  • For pears, spray the whole plant at a concentration of 25-50mg/L after the petals fall to 5-7 days after the petals.

For Root Growth:

Usually, 1-Naphthylacetamide is mixed with other plant regulators, mainly used to promote the rooting of apples, pears, peaches, grapes, and ornamental crops.

The usual formula is as follows: 1) 1-Naphthylacetamide(NAD) + NAA + Thiourea; 2) 1-Naphthylacetamide(NAD) and mixed use of IBA and NAA.
