Pechay Integrated Pest Management
This is from my subject CRPT 2 (Crop Protection)
Pechay (Brassica chinensis L.) is an erect, biennial herb,
cultivated as an annual about 15-30 cm tall in vegetative state. Seeds are 1 mm in diameter and are reddish to
blackish brown in color. Is used mainly
for its immature, but fully expanded tender leaves. Is used as main ingredient for soup and
stir-fried dishes.

You can control this pest of pechay by the following:
v Indirect Methods
o Destroy weeds that serve as breeding places of the
pests.
o Plowing or burning remnants of a crop after harvest.
o Planting the crop at the right season.
o Keeping or maintaining the growing crop in good health
conditions with adequate fertilization and proper watering.
o Protecting the natural enemies of the pests like
birds, etc.
v Direct Methods
o Mechanical
v Crushing the pests with the hands
v Catching the pests with the use of nets
v Trapping
o Chemical
v Dusting with chemicals is a direct control measure
especially when insect pests are so abundant that they inflict heavy damage on
the crop.
That’s all …
Thank You
