MANGO is often a favourite with the gardeners. Those who can have more area for gardening, go in for various varieties like Dasehri, Langra, Chausa and even Baramasi. In addition at the Gangian, Regional Fruit Research Station of Punjab Agricultural University, there are many varieties which are meant to be sucked.
Mango, which bears excellent fruit in this region has, however, earned a bad name for itself as it fails to bear normal crop year after year. Natural calamities like hail storms, strong winds, natural fruit drop and malformation disease have defied a solution for years but a failure at the first stage —fruit setting stage — can be checked effectively.
identified by the appearance of swelling at the base of the leaf and
the presence of small clustered leafy shoots. Malformation in bearing
trees is identified by a thickening of floral shoots that also have
numerous branches. In both cases the bunches seem to be a confused
mass of vegetation. An easy way out is to remove the affected shoots
every month and destroy them. This is essential as the old hanging
malformed shoots are carriers of diseases and insects.
Another important and serious problem is powdery mildew disease. It also appears at the same time. Flowering parts and bunches have a white powdery mass on them which turns the bunch brown and then black as the disease advances. Flowering shoot starts dying, flowers and newly set fruit drop and what is left behind is a naked twig.
The above-mentioned problems cause almost 100 per cent failure in mango. Do you want to check on this statement? Follow the following measures and see for yourself.
In case there is good flowering, there
is no reason why the mango should not bear a full crop. Natural
calamities are beyond one’s control but the insect and other diseases
can be dealt with effectively. At the end of February and end of March
you must spray Thiodan 35 EC (endosulfan) in a ratio of one and a half
millilitre to a litre of water. Do not worry, this will not harm your
blooms. The other malady, that is powdery mildew fungal disease, can
also be effectively controlled by spraying Karathane in a ratio of one
millilitre to a litre of water before and during flowering and after
fruit formation. Another spray can be given if need be. Both Thiodan and
Karathane can be sprayed together. But make sure you reach each and
every part of the tree as these sprays are effective only on contact.
The unsprayed portions may not show any results. Also as the disease and
insect spread easily, advise your neighbour too to take plant protection
