Marigold Pest Control Guide

Aphids, beetles, weevils, leaf hoppers, and red spider mites are common pests that damage marigold plants. Aphids suck plant sap and cause weakness, spraying insecticides every 10-15 days can control them. Beetles and weevils feed on young leaves and shoots, spraying systemic insecticides on leaf undersides controls them. Leaf hoppers roll and curl leaves and wilt shoots, spraying methyl parathion or quinalphos controls the infestation. Red spider mites suck sap and cause speckling and discoloration of leaves, spraying miticides kelthane or dicofol is effective.

Marigold

Pests
Aphids :
These are small insects green to bluish-grey or black in colour. These usually occur in clusters and
damage the apical growing portion by sucking the plant sap. Infected plants become weak and
unproductive. Spraying of insecticides can control the attack.
Control: Spraying of Monocrotophos 0.05%, Phosphamidon 0.02%, or Dimethoate 0.03% at 10-15
days interval helps to check the population of the aphids.

Beetles and Weevils :


These cause damage to number of annuals including marigold. These feed on young leaves and
tender shoots, particularly at the ground level.
Control: Spraying of systemic insecticides like Roger or Monocrotophos @ 2 ml/ litre of water on the
under surface of the leaves effectively controls the insects.

Leaf Hoppers :
Leaf hoppers cause considerable damage to the foliage of the plant, particularly during rainy season.
The symptom appears as rolling and curling of leaves along with wilting of shoots. French marigold is
more susceptible than African type. Spraying of systemic insecticides can control the insects.
Control: the pest is effectively controlled by two to three sprayings of Methyl Parathion or Quinalphos
(0.05%) as soon as the pest infestation is observed.

Red Spider Mites :


These are spinning creatures, red and brown in colour. The mites become active during the flowering
period. They suck the sap from the leaves. The speckling, discoloration and dusty appearance of the
leaves easily identify the attack.
Control: Spraying of miticides like Kelthane (2 ml/litre of water) or Dicofol (0.1%) is effective against
the mites.
