Frost/freeze injury ice crystals forming inside the cell walls causing the cell to explode the plant ofton becomes disfigured in the leafs, blooms, and some times the steams

Iron deficiency (chlorotic) color between veins began to die leaves become yellowish to white

Leaf Scorch (drought/ winter burn) caused by transplanting, soil compaction, nearby excavation, a nutrient deficiency, chemical injury, unfavorable weather conditions (such as drought), poor soil, or limited room for root growth

Chemical Damage Chemical injury is recognized by the curling, twisting or other distortions of the shoots and leaves. Plants usually will grow back to their normal state unless a heavy herbicide dose has caused severe dieback.

Sucking Insect Damage remove cell contents or sap and thereby weaken the plants. aphids, leafhoppers, scales

Nitrogen Deficiency occur when woody material such as sawdust is added to the soil Soil organisms will utilise any nitrogen in order to break this down, making it temporarily unavailable to growing plants. Cold weather, especially early in the season, can also cause a temporary shortage.

2,4-d injury cause injury to neighboring cotton causes of 2,4-D injury are: vapor drift, spray drift and sprayer contamination.

Chewing Insect Damage eat plant tissue such as leaves, flowers, buds, and twigs often seen by uneven or broken margins on the leaves, skeletonization of the leaves, and leaf mining beetle adults or larvae, caterpillars, etc.

Disease Damage rapid and general killing of leaves, flowers or stems A dead area on a stem surrounded by living tissue Yellowing of normally green tissue due to partial failure of chlorophyll to develop A localized spot of diseased tissue Whitish or grayish coating of fungal strands Decayed or decaying tissue caused by microorganism activity.

Mechanical Damage stems or roots have been broken or girdled or if the leaves have been bruised, punctured
