June  month orange malta



    orange malta For the establishment of new orchard suitability of the soil needs to be examined.


The soil depth should be a minimum of 1 meter but equally high-performance orchards can be established on soil depth measuring even less than 1 meter provided precision-based cultural practices including the fertilization program are adopted.


The soil site should preferably be well-drained, clay less than 60%, pH less than 8.3, free calcium carbonate less than 12% and water table of the area more than 2 meters should be selected.


     The pits excavated during the month of May may be filled up by a mixture containing 2 parts soil, one part sand, and 1 part farmyard manure. In addition, add 1 kg Single superphosphate, 1 kg of neem cake, and 100 g Chloropyrifos powder in each pit.


    Nurseryman of citrus should start filling polythene bags with a mixture of garden soil, FYM, and sand. Proper perforation for water should be done on the bags adequately.


     In case trees on stress received rainfall during the stress period chlormequat chloride a growth retardant at the rate of 2 ml per liter of water should be sprayed on the trees. the Second spray should be applied after 20 days.


    For increasing the fruit size of the Ambia crop and if there is a wide gap of more than a week between two spells of rains spray potassium nitrate at the rate of 1.5 kg + 2, 4, D 1.5 gms per 100 liters of water.


    Irrigate the trees for taking Mrig Bahar, if rains are inadequate or not commenced on time. A drip system of irrigation can also be started to break the stress to the trees. To avoid water stagnation near the tree trunk, level the soil around the tree trunk. Drainage channels (trenching size: 30cm depth, 45 cm top width, and 30 cm bottom width) after every 2 rows of plants along the slope should be prepared to remove excess water from the orchard in the rainy season. The laterals of the drip system should be wound up. After the monsoon starts the mulch from the tree basin should be removed.


     Apply Bordeaux paste on the tree trunks if not applied earlier to control Phytophthora disease on citrus. Prepare the paste by mixing 1 kg lime and 1 kg copper sulfate in 5 liters of water separately overnight in a plastic container. The next day mix both the mixtures in another container so that the color of the paste is sky blue. Test the mixture by dipping the iron rod to see the presence of copper coating. Apply with a paintbrush on the tree trunk up to 24 inches from soil level. This paste should be applied within 12 hrs after mixing.


     During this month there is the rapid spread of citrus canker hence the affected leaves, branches should be pruned and burnt. Spray copper oxychloride 180 gm with streptomycin 6 gm in 60 liters of water before the onset of the monsoon. Repeat the spray 3-4 times at an interval of 30 days.


     To check fruit drop of Ambia bahar spray the Santa trees with 1.5 gms 2, 4-D or gibberellic acid (GA). 100 gms carbendazim 50 wp with 1 kg urea in 100 liters of water. Repeat the spray after 15 days if the fruit drop continues.


     Citrus trees affected with Phytophthora, spray Mefenoxam M Z-68 (Metalaxyl 4 % + Mancozeb 64 %) @ of 2.50 gm/ lit water as a preventive measure to control the disease.


      Incidence of Citrus Psylla on the new leaves of Mrig bahar can be managed by spray dimethoate 2 ml or imidacloprid 0.5 ml or quinalphos 1 ml or acephate 1 g thiamethoxam 0.3 g in one liter of water. Repeat the second spray after 10-15 days interval.
