Common Marigold Plant Damaging Pests
Important Points for Beginners to Identify and Manage Pests in Marigold Plants
- Identifying the pest: The first step is identifying the pest infesting your marigold plant so that you can approach it with the most effective control method.
- Regular Monitoring: Monitor your Marigold plants regularly for signs of pests. This will help you to identify an infestation early when it is easier to control.
- Sanitation: Remove the infected plant debris and burn them.
- Natural Control: Several natural control methods can help to manage pests. These include plant extracts, essential oils, predators, and organic insecticides.
- Chemical Control: If natural controls are ineffective, use insecticides as a last resort, and follow the label instructions and dosage carefully.
Aphid Pest in Marigold Plant
- Damage Symptoms by Neotoxoptera oliveri: Aphids extract the sap from plant tissues, causing stunted plant growth or distorted flowers. Infested leaves exhibit wilting, curling, and chlorosis. Aphids excrete sugary honeydew as a byproduct of their feeding, promoting the growth of black sooty mold.
- Survival and Spread: Aphids prefer moderate temperatures and high humidity of 15-27°C for their growth and development. High humidity facilitates their feeding and reproduction. They prefer actively growing, particularly succulent plant tissues.
- Treatment, maintenance, and Control Measures: Spray bifenthrin, cypermethrin, deltamethrin, malathion, chlorpyrifos, dimethoate, methyl demeton, monocrotophos, phosphomidon, imidacloprid, thiamethoxam, clothianidin, and acetamiprid.
Thrips Pest in Marigold Plant
- Damage Symptoms by Thrips tabaci: Thrips feed on the upper surface of marigold leaves and cause a stippled or speckled appearance called silvering or whitening. The affected plants may show twisting and curling in leaves, scarring on petals, and deformed flowers.
- Survival and Spread: Thrips prefer warm and dry environments of 20-30°C for survival and reproduction. Dense canopy and poor airflow provide hiding places and shelter for thrips, allowing them to multiply and move between plants easily.
- Treatment, maintenance, and Control Measures: Spray imidacloprid, acetamiprid, thiamethoxam, acephate, chlorpyrifos, bifenthrin, cypermethrin, deltamethrin, spinosad, methoxyfenozide, and diflubenzuron.
Slug Pest in Marigold Plant
- Damage Symptoms by Deroceras reticulatum: Slugs feed by scraping and chewing on the leaves of marigold plants. Slugs produce slimy mucus as they move across plant surfaces. The affected leaves show wilting, chlorosis, and stunted growth.
- Survival and Spread: Slugs prefer moderate temperatures and damp climates of 10-20°C for reproduction and increased pest activity. They prefer areas with ample organic matter, shade, and dense vegetation, such as decaying leaves or plant debris.
- Treatment, maintenance, and Control Measures: Spray metaldehyde, iron phosphate, copper sulfate, and copper oxychloride.
Leaf Miner Pest in Marigold Plant
- Damage Symptoms by Liriomyza trifolii: Leaf miners create distinct serpentine or winding mines on the surface of the leaves. These mines appear as thin, white, or yellowish lines. The affected leaves show discoloration, deformation, stunted growth, and premature leaf drop.
- Survival and Spread: Leaf miners prefer warm temperatures of 20-30°C and high humidity. They prefer plants in the vegetative growth stage. Plant stresses and nutrient deficiencies provide an ideal environment for leaf miners to feed and reproduce.
- Treatment, Maintenance, and Control Measures: Spray bifenthrin, cypermethrin, malathion, spinetoram, spinosad, abamectin, triazophos, monocrotophos, imidacloprid, acetamiprid, indoxacarb, and thiamethoxam.
Red Spider Mite Pest in Marigold Plant
- Damage Symptoms by Tetranychus urticae: Red spider mites feed on the p
