The experiment was conducted at Fruit Research Station, BARI, Binodpur, Rajshahi during 2012 on bombay litchi variety to develop an appropriate management practice against litchi mite. Results showed that the lowest leaf infestation (5.21%) was observed in T1 = (two pruning of infested foliage-first on June after harvesting of fruits and second on August + spraying of Abamectin 1.8 EC (Vertimec 1.8 EC @ 1.5 ml/litre of water in February before opening of flowers), which is statistically different from other treatments and the highest leaf infestation (35.61%) was recorded in Untreated control. The leaf infestation of other treatments was ranged from 7.92–12.29%.

Pest Management
To find out the most effective method of managing litchi mite
The experiment was conducted at Fruit Research Station, BARI, Binodpur, Rajshahi during 2012 on bombay litchi variety to develop an appropriate management practice against litchi mite following randomized complete block design with five treatments and three replications. The treatments were as follows: T1 = two pruning of infested foliage-first on June after harvesting of fruits and second on August + spraying of Abamectin 1.8 EC (Vertimec 1.8 EC @ 1.5 ml/litre of water in February before opening of flowers, T2 = two pruning of infested foliage-first on June after harvesting of fruits and second on August + spraying of wettable sulphur (Thiovit 80 WP @ 2.0 g/litre of water in February before opening of flowers, T3 = two pruning of infested foliage-first on June after harvesting of fruits and second on August + spraying of Dimethoate 40 EC (Tafgor 40 EC @ 2.0 ml/litre of water in February before opening of flowers, T4 = two pruning of infested foliage-firstt on June after harvesting of fruits and second on August, and T5 =Untreated control. A single tree was considered as a treatment replication. Sprays were done using power sprayer. In each tree, a small branch was randomly selected and the number of infested leaves, infested inflorescence were counted and recorded. Collected data were transformed statistically when necessary.
Annual Report 2012-2013, Entomology Division, BARI , Gazipur
70,000.00
Pruning of infested foliage + Spraying of Abamectin 1.8 EC (Vertimec 1.8 EC @ 1.5 ml /L of water) was found most effective which offered the highest reduction of leaf and inflorescence infestation (85.37% & 74.86%, respectively) over control.
