Abstract/ Executive Summary:

To develop an integrated management approach for the destructive citrus leaf miner, Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae), several management options were evaluated during 2009 at Hill Agricultural Research Station, Khagrachari. Two botanicals (neem oil and neem seed extract), two chemical insecticides, namely Perfekthion 40 EC (dimethoate) and Ralothrin 10 EC (cypermethrin) with untread plants were evaluated at pre-determined doses. The lowest infestation was recorded from the plants treated with Perfekthion 40 EC (6.48%). Accordingly, the highest percent reduction of leaf infestation over the untreated control was found from Perfekthion 40 EC (90.82%).

Keywords: Citrus, leaf miner, Lemon, Perfekthion 40 EC

Location: Khagrachari

Start Date: 02-03-2009

End Date: 02-06-2010

Program Area: Pest Management

Commodity: Lemon

Objectives:

To find out the suitable management option for the control of citrus leaf miner.

Methodology:

The research work was conducted at the mandarin orchard of Hill Agricultural Research Station, Khagrachari during summer 2009. The experiment was laid out in RCB design with five treatments and 3 replications. One mandarin tree was considered as one replication of a treatment. Around five year old lemon trees were used in this stydy. The treatments used in this experiment were as follows T₁= Spraying of Neem seed extract @ 50 g/litre of water starting from new flashing at 10 days interval; T₂= Spraying of Neem oil @ 5 ml/ litire of water mixing with 5 ml trix starting from new flashing at 10 days interval; T₃= Spraying of Imidacloprid 200 SL @ 1 ml/ 4 litre of water starting from new flashing at 10 days interval; T₄= Spraying of Dimethoate 40 EC @ 2 ml/ litre of water starting from new flashing at 10 days interval; T₅= Spraying of Cypermethrin 10 EC @ 2 ml/ litre of water starting from new flashing at 10 days interval and T₆= Untreated control. Each treatment was applied twice as a full cover spray on mandarin trees with the help of high volume knapsacks sprayer. The first application was done within 7 days of new flushing at the first sight of infestation and the second application was done after 10 days of first application. Each insecticide was used at a pre- determind single dose. In each replication, ten twigs were randomly selected and tagged and the number of infested and healthy leaves for each treatment was recorded. Data were analyzed statistically.
