Always use good quality sticker/spreader in spray solution

*For controlling aphid on newly emerging leaves and flowers use Imidacloprid/confidor @ 200ml/200L water.

** If mealy bug attack appears spray formulation of Bauveria bassiana or Verticillium spp. (Meal Kill) @ 600 – 1000g/200L water.

For the control of wilt (yellowing of leaves and branch drooping)

  • Remove the affected stem. Make a shallow pit around collar region and drench with propiconazole (Tilt/Dhan) 2ml/L or carbendazim (2g/L) twice at 10 days interval. Put at least 20 L solution per tree. 
  • A spray schedule consisting of companion @ 0.25% followed by difenoconazole (score)/tebuconazole (folicur) @0.015% followed by mancozeb (Dithane M-45) @ 0.25% along with sticker at 15 days interval has been recommended for the control of stemphyllium disease in garlic.
  • Four applications (at petal fall, walnut and twice at 15-20 days after walnut stage) of summer oils (Orchex 796, DC Tron, IPOL (summer) and Shelter 909) @ 1.0% control mite in apple at moderate to low populations under field condition.
  • Timing of two applications of insecticide chlorpyriphos (0.04%) starting at 450-475 day degrees only on infested apple trees provided excellent control of scale populations during summer. Summer oils were found as effective as other miscible oils (HPSO and SERVO) @ 2.0%.
  • A spray schedule for effective management of foliar and fruit insect pests/mite in apple has been formulated and recommended.
  • Effective management of the root borer can be done by i) Drenching with chlorpyrifos (0..1%) up to 1.25m radius around the tree trunk in October – November and March. ii) Mixing of insecticidal dust @ 300gms per tree from mid-June to Mid July. iii) Killing of the adult beetle by installing the light traps inside the orchard. iv) Mechanical killing of the grubs by exposing the roots of infested trees
  • Buds and flower damaging beetles in apple and pear have been effectively controlled by the application of methyl parathion (0.05%) /Chlorpyriphos (0.04%)/monocrotophos (0.04%) once or twice at a weekly interval before flowering.
  • Methods for scientific management of Apis cerana indica honey bees have been developed and promoted among local bee keepers. A fixed beehive with movable frames has also been designed to keep cerana bees in fruit orchards.
  • An Agromet Observatory has been established with the help of IMD during 1992. Based on the forecast received from Super Computer (Pune) under National Medium Range Weather Forecasting System, an Agromet Advisory Bulletin is prepared and released every week on Tuesday since 1995 through print and electronic media for the benefit of local growers.
