Cotton Disease Treatment

1. Cotton Anthracnose

Cotton Anthracnose pathogen belongs to imperfect fungi subphylum. Sexual state is small clum of cotton shell Glomerella goss. Anthrax in cotton seedling disease, causing seedling blight.

Symptoms

Cotton anthracnose could be occur each growth stage, seedling and boll stage will be most damaged.

1. Seedling: after germination, seedling disease can cause pre-emergence rotten kind of victimization, not unearthed and death. Seeding emergence, stem base appear reddish-brown to purple-brown streak, after expanding brown, slightly sunken, sever dehyrathion diastema, lodging seedling death. Wet spots on the orange slime produced, namely conidia. Cotyledons disease, and more students semicircular borwn spots in margin, reddish brown after drying off the edge of the cotyledons incomplete.

2. Adult-plant stage: this stage the major damage bolls, leaves and stems are rarely sick. Leaf disease lesion was not the whole round, easy to dry cracking. Stems killed, reddish brown to dark spots black, round or elongated, central depression skin breakdown, often exposed xylem, diseased case of wind easily broken. Bolls disease, newborn purple dot, then gradually expanded to round or nearly round brown spots, slightly sunken. Wet central lesions produced in slightly Physalospora orange and adhesive conidia group. Lesion can be interconnected to expand to full rings. Bell immature fibers within some or all of rot and become stiff dark yellow petals.

Solutions

Crop science company has accumulated rich experience and could offer the corresponding high-class solutions, e.g.: the series of CALIBUR PRO, DIPMA 28% SC.

2. Cotton Greensickness

Cotton Greensickness is caused by Verticillium wilt pathogens (Verticillium albicans and Verticillium dahliae). Mainly damages the stems, branches and leaves of cotton. The disease spreads widely, including cottonseed, diseased plant residues, soil, fertilizer and water, agricultural tools and other media. In the light cases, the leaves turn green and yellow, the buds fall off, and the yield is seriously reduced.

Symptoms:

Cultivation, from about 1 months after planting, symptoms occured on the ground part, the disease will be last until the end of the harvest. Firstly, the lower leaves partial wilting, leaf side curly. 2-3 days later, disease from yellowish white to yellow. Leaf margin discolor more, the veins as the center is wedge-shape. Next discolored parts gradually expanded, the whole piece of leaf yellowing, browning die slowly. Disease exacerbations, upper leaves were dead and lead to lower leaf chronic wilt. Therefore, plant height will be shorter, fruit set and growth significantly affected.
