The Centre of Plant Protection Studies of Tamil Nadu Agricultural University has forecast pest and disease control methods for August in certain districts of the State.
Since the pest and disease incidence will be below the economic threshold level in all districts of Tamil Nadu, farmers are asked to monitor the crops for pest activities by setting light traps and yellow sticky traps in their fields.
Recommendations have been made for the benefit of rice farmers growing samba rice in Cauvery delta zone and other rice growing areas in the State.
In the nursery, thrips and caseworm are the major insect pests to be expected, and in diseases, brown spot and blast are expected to be visible. To manage these, farmers are asked to treat the seeds with Carbendazim 2g / kg or Pseudomonas fluorescens 10 g / kg of seeds in one litre of water overnight before sowing.
Application of Pseudomonas fluorescens at 1.5 kg / 20 cent nursery along with 30 kg farm yard manure, 48 hours before pulling out seedlings is advocated.
For seedling root dip, select 25 sq metre area in the main field and stagnate water up to a depth of 2.5 cm at one corner and dissolve 2.5 kg of Pseudomonas fluorescens. In this stagnated water, dip 20 cent nursery seedlings for 30 minutes and transplant.
For managing insects, set up light trap to monitor adult moths and other insect pests, spraying NSKE 5 per cent with sticking agent at 5 ml / litre, apply neem cake at 12.5 kg / 20 cent nursery as base dose, and spray either neem oil three per cent or chlorpyriphos 20 EC at 2 ml / litre of water, if needed.
If dry weather continued due to delay in monsoon, there was a possibility for multiplication of jassids, thrips, whitefly, spiralling whitefly and different species of mealy bug including papaya mealy bug.
Farmers are asked to monitor sucking pests by installing yellow sticky traps at 5 / acre and if needed to spray neem seed kernel extract 5 per cent of fish oil resin soap at one kg in 40 litres of water.
