31. Control
1. Biological control
• Ladybugs
• Green lacewing
• Wasp

32. 1. Chemical control
• Insecticidal soaps and oil
• Pyrithrins
• Nocotine sulfate
• Rotenone

33. Aglaonema Modestum
• It is are mainly found in the Philippines and
Malaysia.
• Commonly known as Chinese Evergreen.
• Aglaonema growth is very slowly.
• This is best for indoors or where the
temperatue will not drop below 45 degre.
• These plants have large glossy oval-shaped
leaves and small flowers, which colors change
from white to greenish white or even red.

34. Injury by:
oMealy bugs generally resemble tiny white pieces of
cotton gathered together on stems and leaves.
oA mealy bug infestation results in stunted growth,
premature foliage dropping and discolored leaves.
o Adult mealy bugs fly around the plant.
1. Mealy bugs:

35. oPlacing yellow sticky cards near the Chinese evergreen
can help lower their numbers.
oFor small mealy bug infestations, wipe the pests off the
plant with a cotton ball dipped in rubbing alcohol.
oHorticultural oil, insecticidal soaps and Neem oil will
control larger mealy bugs infestations.
oIf the Chinese evergreen is located outdoors, it can help
to introduce predatory insects like ladybugs and green
lacewings, to feed on the pests.
Controls:

36. oSpider mites are about the size of a pinhead, which
makes these pests difficult to see.
oSign of spider mites is webbing on stems and leaves of
the Chinese evergreen.
oSpider mites feeds on plant’s cell content, leaving
discolored spots on the foliage.
2. Spider mites:

37. Controls:
oSmall infestations are generally just an
annoyance and are controlled by wiping the
mites off the plant with a damp paper towel.
o Larger infestations results in withered, yellow
foliage that drops prematurely and is controlled
with horticultural oils and insecticidal soaps.
oSpider mites tend to attack water-stressed
plants, so regularly watering, but not over-
watering, the Chinese evergreen will prevent
spider mites from attacking the plant.

38. oAphids are a soft-bodied insect that feast on the vital
fluid flowing through the Chinese evergreen.
oIn small numbers, aphids do little to no major
damage.
oHowever, a larger infestation will stunt the plant’s
growth, distort the leaves and cover the evergreen in
honeydew, a sticky substance that leads to powdery
mildew.
3. Aphids:

39. Controls:
oControl aphids by wiping them off the houseplant
with a cotton ball dipped in rubbing alcohol.
oIf the plant is located outdoors, spray the aphids
with a water hose to force them off the plant.
o Larger infestations are controlled with insecticidal
soap.

40. Snapdragon
• The Snapdragon’s botanical name is
Antirrhinum, from the Greek words ‘anti’
(like) and ‘rhin’ (a nose).
• Snapdragons come in a wide variety of
bright colours and a range of heights, from
dwarf to medium and tall.
• Snapdragons are typically available in the
spring and summer months.
• They can be used as colorful garnish along
side salads, spring rolls and fruit plates or
on specialty cocktails.

41. Injury by:
oCaterpillars cause much damage, mainly by eating
leaves, leaving holes, and ragged edges in their wake.
Controls:
oThe best way to control caterpillars is to hand-pick
them from the plant or from their hiding places at the
base of the plant, and either relocate them outside
the garden or drop them into a bucket of soapy water.
1.Chewing Pests:

42. Cymbidium Orchid
• Cymbidium orchids are often
called “boat orchids”
• The flowers are usually large in size
and display a patterned lip.
• The flowers can last anywhere
from 8-10 weeks and they come in
almost all colors except blue.
• Cymbidium orchids are popular
due to their ability to thrive in
cooler, drier conditions.
• Cymbidium orchids is successfully
grow in mild temperatures and no
frost conditions.

43. Injury by:

o Adult mealy bugs fly around the plant.
2. Mealy bugs:

45. oPlacing yellow sticky cards near the cymbidium orchids
can help lower their numbers.
oFor orchids with mealybugs on their roots, remove the
orchid from the pot, soak the roots in a solution of
insecticidal soap for a few hours, then repot in a clean
new pot with new potting material.

46. Natural Pest Control Methods
The Tasteful Garden promotes natural pest control methods such as
keeping your garden clean and weeded, using mulches and good
compost in the soil.
Many diseases are spread by splashing water so water sprinklers and
heavy rains can create molds, fungus', and bacterial diseases which can
make your plants very unhappy and sometimes can kill them. Mulching
with dried leaves, pine straw, hay straw, grass clippings, newspaper, and
even cardboard can make all the difference in keeping diseases under
control. They can also help hold in moisture and protect from
overheating the soil in the hot summer months. This keeps plants
happier and healthier and can prevent stressful conditions which invite
infestations of insects.
