Weed Control<\/strong><\/span><\/p>\n\n- Application of Diuron<\/a> as a pre-emergence weedicides spray @ 1.2 kg\/acre twice at 120 days interval is quite effective to control weeds up to 280 days.<\/li>\n
- For post-emergent control, use of 2,4-D (Fornoxone) @ 2 kg\/acre in 200 litres of water followed by a composite spray of 1 litres of Paraquat<\/a> (Gromaxone) plus 0.6 kg 2,4-D (Fornoxone) in 200 litres of water\/acre 10-20 after the first spray is quite effective in controlling weeds. The composite spray of Paraquat and 2, 4-D may be repeated twice at 30 days interval, if needed. It controls\/reduces the weed growth for about 4\u00ad month.<\/li>\n<\/ul>\n

Pest Control<\/h2>\n\n<\/p>\nPests<\/strong><\/p>\nLeaf minor:\u00a0<\/strong>Spray Dichlorvos 76 WSC @ 1 ml \/ lit or Dimethoate 30 EC 2 ml \/ lit or Fenthion 100 EC @ 1 ml \/ lit or Monocrotophos 36 WSC @ 1.5 ml \/ lit or 5% of Neem Seed Kernel Extract (NSKE) or Neem oil 3%.<\/p>\nCitrus Psylla:\u00a0<\/strong>Prune affected shoot and destroy. Spray Monocrotophos (0.057%), Dimethoate (0.057%) and phosolane (0.057%) twice at an interval of 10-12 days. First spray should coincide with the emergence of new flush.<\/p>\nCitrus Butterfly:\u00a0<\/strong>Spray Monocrotophos (1.5 ml\/liter of water) or Dichlorvos (1 ml\/l) Or Dimethoate (1.5 ml\/l) or Carbaryl (2g\/l) or Endosulphon (4ml\/l) or Bacillus thuringensis (Dipel) (0.057%) at early stages of the pest.<\/p>\nAphids<\/a>:\u00a0<\/strong>Prune infested shoots at the initial stages of infestation. Spray systemic insecticides like Monocrotophos (1.5 ml\/l) or Dimethoate (2ml\/l) or botanical insecticides like neem oil (1%) of mahwa oil(1%) or pongamia oil (2%) at emergence of new flush or flowers<\/p>\nMealy Bugs<\/a>:\u00a0<\/strong>Prune infected shoots and destroy. Spray neem oil (2%) or pongamia oil (2%) twice at an interval of 15-21 days as and when the pest makes its appearance.<\/p>\nScales:\u00a0<\/strong>Spray Monocrotophos (2ml\/l) Methyl demeton (2ml\/l) or Carbaryl (3g\/l).<\/p>\nThrips<\/a>:\u00a0<\/strong>Make soil application of Fipronil<\/a> \/ Spray Actra (0.05%) or Phosphomidon (0.05%) during emergence of new flush.<\/p>\nFruit flies:\u00a0<\/strong>Collect and destroy the infested fruits, use poisonous baits. Male attracting traps (baits) containing methyl eugenol (0.1%) and Malathion (0.05%) reduce fruit flies population when used 60 days before harvest.<\/p>\nFruit sucking moth:\u00a0<\/strong>Collect and destroy the infested fruits at regular intervals. Arrange light traps in the nights with poisonous baits having a mixture of Malathion (1ml) + sugar (1%) + fruit juice.<\/p>\nCitrus root nematode:\u00a0<\/strong>Apply Pseudomonas fluorescens at 20 g per tree at a depth of 15 cm and 50 cm away from the trunk for the management of slow decline due to the citrus root nematode (Tylenchulus semipenetrans). Soil application of Phorate @ 2 g followed by drenching with Metalaxyl <\/a>plus Mancozeb<\/a> 72 WP @ 0.1% 50 ml \/ poly bag \/ kg of nursery soil for citrus decline.<\/p>\n\n<\/div>
Disease Control<\/h2>\n\n<\/p>\nPhytophothora Gummosis:\u00a0<\/strong>Scraping of the affected area and application of Bordeaux paste or copper oxy chloride paste or Ridomil (3 g) + Carbendazim<\/a> (1 g)<\/p>\nCitrus greening:\u00a0<\/strong>Removal of infected branches\/unproductive trees and their replacement by disease-free plants. Application of Streptomycin<\/a> 600 ppm with ZnSO4 and FeSO4. Meticulous control of citrus psylla vector.<\/p>\nCitrus Tristeza virus:\u00a0<\/strong>Control of aphids and use of cross protected grafts and shoot tip grafted plants or disease free grafts are recommended.<\/p>\nCitrus canker:\u00a0<\/strong>Cutting of infected twigs followed by spraying of 1 % Bordeaux mixture or copper fungicide. Foliar spray application of 100 ppm streptomycin sulphate is also effective.<\/p>\n
