Transcript Pesticide use in Tomato IPM

Pesticide use in Tomato IPM
•Natural enemies are an extremely important
component of integrated pest management of tomato
insects and mites.
•Insecticides are useful component of IPM programs
because of their convenience, simplicity, effectiveness,
flexibility and economy.
•Using selective insecticides to kill the target pest
without killing natural enemies helps maximize as well
as integrate chemical and biological controls.
•Nonselective insecticides, can be made more selective
by careful application rates, timings and coverage to
minimize killing natural enemies.
•Products that have a short residual effect on natural
enemies are favored for IPM programs. Consider both
the short-term and long-term effects of an application
when selecting an insecticide treatment.
Nursery preparation
•Before sowing, the nursery beds should be
drenched with 0.2% Dithane M-45 or
treated with Difolaton or captan
•Treat nursery belt with carbofuran 3G
100g/sq m for nematode management
Seed Treatment
•Treating the seeds with Thiram @ 3g per kg
of seeds will prevent the seed born fungal
diseases
•During summer and rainy season, there is a
very heavy incidence of damping off. To
protect seeds and seedlings, the beds should
be treated with 10% formaldehyde.
Seedling treatment
•Before transplanting, seedlings should be treated
with insecticides 0.1% nuvacron and Dithane M-45
0.2%
•Hardening is done by adding 4000ppm sodium
chloride or spraying 2000ppm ccc is effective for
hardening of seedlings
•Application of bleaching powder @15kg/ha
before planting against bacterial wilt infection in
endemic areas
•Spray 40-100ppm streptocycline sulphate on
unripe fruits of tomato to control bacterial spot or
dipping the seedlings 100 ppm streptocycline
sulphate before transplanting.
•Imidacloprid 17.8 SL @25g ai/ha or
thiamethoxam 25 WG@ 25g ai/ha or acetamiprid
20 SP@ 20g ai/ha can be used for managing
sucking insect pests such as aphids, jassids, leaf
hopper and whitefly.
•Spraying of Chlorfenapyr 10 SC@100 g
ai/ha or Fipronil 5 SC@50 g ai/ha for thrips
management
•Friut borers such as Helicoverpa armigera
and Spodoptera litura can be managed by
applying Emamectin benzoate 5 SG@11 g
a.i/ha or Spinosad 45 SC@75g a.i/ha or
Flubendiamide 480SC@48-60gai/ha
•Propargite 570EC @500gai/ha will be
helpful in the management of mite
population in tomato
•Soil drenching of Fytolan @ 4g/l for
managing bacterial wilt disease is advocated.
•Dithane M- 45 2g/l is recommended for to
manage fruit rot of tomato
•Application
of
pendimethylin
@1kg
ai/ha+1hand
weeding
45days
after
transplanting, or Sensor @205kgai/ha or
[email protected]/ha applied after transplanting
are effective to control weeds.
