New molecules / Chemical:
Generated efficacy data for registration of Cyantraniliprole (new molecule) by E.I. Dupont for the management of citrus thrips and citrus leaf miner. Established the field dose of Cyantraniliprole 10.26% w/w OD @ 60 g a.i./ha-1 against thrips and leaf miner. This can be recommended for effective management of these insect pests of citrus below ETL.
-
Integrated Pest Management Modules:
Management of citrus mites using new acaricides. The application of Fenazaquin 10 EC @ 1 ml/l or Spiromesfen 240 SC @ 0.39 ml/l at 15-day intervals starting from 15 days after fruit initiation (two sprays during May–June or August–September) reduces mite damage on leaves and fruits and enhances the number of marketable fruits in citrus. Validated through AICRP(F) at 5 centers.
-
Documentation:
Documented major mites and their bioagents in citrus cultivars. Three species of phytophagous mites were recorded:
- Eutetranychus orientalis (Klein)
- Brevipalpus rugulosus Chaudhri, Akbar & Rasool
- Polyphagotarsonemus latus (Banks)
Additionally observed:
- Tetranychid mites: Schizotetranychus sp., Eotetranychus sp.
- Eriophyid mite: Phyllocoptruta oleivora (Ashmead)
Major bioagents:
- Mallada desjardinsi (Navas)
- Coccinellids: Stethorus sp., Parastethorus indira Kapur (= Stethorus indira Kapur)
- Dipteran midge: Feltiella sp.
- Staphylinid beetle: Oligota sp.
-
Methodology:
Standardized and popularized the mass multiplication technique of predator Mallada desjardinsi to control citrus blackfly. Field release of M. desjardinsi @ 30 larvae or 50 eggs per tree, twice each season, effectively checks insect pests like blackfly, whitefly, psylla, and leaf miner.
-
Development of Organic Package for Nagpur Mandarin Cultivar:
IPM Module I (T4): Foliar spray of Azadirachtin (1%) @ 4 ml/l followed by Lecanicillium lecanii @ 5 g/l and release of Mallada desjardinsi @ 50 eggs/tree at 10–15 day intervals.
IPM Module II: Foliar spray of Horticultural Mineral Oil @ 1% followed by Beauveria bassiana @ 5 g/l and Azadirachtin (1%) @ 4 ml/l.
These were implemented during flushing seasons with five treatments involving modules of nutrient, insect pest, and disease management.
