For insect management in citrus plants, apply 1250 ml monocrotophos 36 SL in 1250 litre water /ha in September. If you haven’t used manure or fertiliser on your guava trees yet, now is the time to start. For wilt disease management, apply 15g Bavistin per plant. It is recommended that a foliar treatment of 2.5 kg ZnSO4 + 5 kg urea in 500 litres of water be made. To control hairy caterpillars in grapes, mix 1.0 L of dichlorwas 76 EC/ha in 1250 liters of water.
By the end of October, apply the remaining half dose of nitrogen (500-600 g urea) to each plant, along with irrigation. Powdery mildew disease is best treated with a foliar treatment of 1 kg sulfex or 500 ml kerathane per hectare in 500 liters of water.
To control bark eating insects, make an emulsion of monocrotophos (10 ml) 36 SL or methyl parathion with water and apply it to the insect’s holes. Spray 5 kilograms ZnSO4 and 2.5 kg slacked lime in 1000 litre water when citrus trees show signs of nutrient shortage. Similarly, spray 1-2 kilograms urea in 1000 L water to recover nitrogen shortage. Citrus canker can be treated with 0.3 percent copper oxychloride sprayed on the plants. The first spray should be done in October, the second should be done in December and third should be done in February.
In the month of November and December, Irrigation should be done every 20 days in orchards. In old orchards, remove dried twigs and branches. Plants should be protected from frost as much as possible. If possible, use irrigation to help alleviate the effects of frost. Stop mealy bugs from climbing mango trees. This can be accomplished by draping alkathene sheets up to a height of one meter on the stem of the pants. By the middle of December, all anole plants should be harvested. Necrosis will be spread due to late harvest. Irrigate guava orchards and keep them under control.
