DNA

Plant growth regulators can be defined as chemical substances that control all the aspects of growth and development within plants.

Plant Growth regulator channelizes the plant growth in order to achieve better yields. By short- ening the nodal length, it results in denser plant and closely placed fruits.

DNA is one of the extensively used regulator which is used especially in mango fruit. Pri- marily, the role of Boost is to inhibit gibberellin synthesis and promote flowering and fruit- ing. Thus, the vegetative growth reduces and theassimilates are transferred to reproductive organs and the yield potential increases.

Pack sizes: 50ml, 100ml, 250ml, 500ml & 1 ltr.

Mode of Action

DNA is taken up into the xylem through the leaves, stem, or roots and translocated to growing sub-apical meristems. It reduces the inter nodes length of new shoots and results in earlier forma- tion of terminal buds hence, controlling the tree vigour. These terminal buds bear fruits, hence, boost increases the fruit bud production, fruit color and harvest yield.

Recommendation:

Mango

Dosage: 15ml/acre
Time of Application: Age 7 to 15 years. Dosage: 20ml/acre
Time of Application: Age 16 to 25 years. Dosage: 30ml/acre

Method of Application

- DNA is much effective when used with Collar Drench method. With the recommended quan- tity of DNA with 0.5-2 ltr of water per tree, apply this on soil or trunk crack line around the base of the trunk.
- Apply DNA as Soil Drench. Dilute recommended quantity of Boost in clean water of 10 ltr and apply in a furrow 5 cm deep about 2 to 3 feet away from the trunk, fill up with soil after application.
- By Foliar Spray Application, the new flowering can be treated with 1000-2000 ppm after the sunset.

Safety recommendations

- Do not use cooking utensils for preparing the spray solution. - Do not spray if the rains are expected.
- Do not enter the application area within 24 hrs of application. - Do not use empty packaging for any other purposes.
