Cotton Pest & Disease Management | Insecticide & Miticide Efficacy

Causes circular lesions that coalesce, reducing leaf area and triggering premature defoliation.

• Brown to purple bordered circular spots on leaves
• Premature leaf drop
• Reduced photosynthetic capacity and boll filling

Vascular fungal disease causing systemic wilting, vascular browning, and premature plant death in severe cases.

• Yellowing of lower leaves progressing upward
• Dark brown vascular discoloration inside stems
• Stunting, wilting, and premature plant death

Major destructive pest feeding directly on flowers, squares, and developing bolls. Larval feeding destroys cotton fibers, ruins boll development, and causes catastrophic yield losses.

• Entry holes and chewed damaged areas on squares and bolls
• Larvae feeding inside bolls causing internal tissue rot
• Decreased fiber quality and premature boll drop

Sap-feeding insects that drain plant vigor, distort foliage, and excrete sticky honeydew that fosters sooty mold on open lint fibers, severely degrading cotton grade.

• Curled, distorted leaves and stunted vegetative growth
• Heavy sticky honeydew and black sooty mold on leaves and open lint
• Midday wilting and plant stress; acts as vector for plant viruses

Green looping caterpillars (1–1.5 inches). Alfalfa loopers appear in May–June; cabbage loopers arrive in late summer. Caterpillars chew foliage, leaving a ragged canopy.

• Ragged leaf appearance from foliar chewing
• Irregular holes through lower and mid-canopy leaves
• Early-season defoliation under high pest pressure

Green caterpillars (~1 inch) with light lateral stripes and dark spots near front legs. Build up on surrounding weeds/crops, migrate into fields, skeletonize leaves under webs, and chew squares and young bolls.

• Young larvae skeletonizing leaves under thin protective webs
• Older larvae chewing large holes in leaves, squares, and small bolls
• Destroyed flower buds, delayed maturity, and reduced yield

Moth larvae (green to reddish-brown with tiny body spines) that bore directly into cotton squares and bolls, depositing frass and destroying developing seed and lint.

• Frass-filled entry holes in squares and developing green bolls
• Premature shedding of young fruit forms
• Destroyed young fruit, delayed maturity, and direct lint yield loss

Small grayish moth whose larvae bore into bolls beneath the calyx, feed on seeds, and cut/stain lint fibers. Bolls rot or open prematurely with severely degraded fiber grade.

• Larval entry holes beneath green boll calyxes
• Cut, stained, and discolored lint fibers inside developing bolls
• Prematurely opened, rotted, or hard-locked bolls

Microscopic soil worms that penetrate root systems and form galls, blocking water and nutrient uptake. Synergizes with Fusarium wilt to create lethal disease complexes.

• Swollen knots and galls along root systems
• Stunted growth, patchy yellowing, and persistent midday wilting
• Reduced boll counts and heightened vulnerability to vascular wilts
