    en.wikipedia.org/wiki/Maize_lethal_necrosis_disease

    As the disease advances, the maize leaves become yellow and dry out from the outside edges towards the midrib. MLND can also cause dwarfing and premature aging of the plants. Finally, the entire plant dries out and dies. Dead plants can then be seen scattered across the field among healthy looking plants.

    A plough or plow (both pronounced / p l aʊ /) is a farm tool for loosening or turning the soil before sowing seed or planting.

    en.wikipedia.org/wiki/Corn_grey_leaf_spot

    Corn grey leaf spot can be an extremely devastating disease as potential yield losses range from 5 to 40 US bushels per acre (440 to 3,480 L/ha). At higher disease levels, even greater losses can result. When a corn plant's ability to store and produce carbohydrates (glucose) in the grain is diminished, yield losses take place.

    It is based on in-depth understanding of chemical ecology, agrobiodiversity, plant-plant and insect-plant interactions, and involves intercropping a cereal crop with a repellent intercrop such as Desmodium uncinatum (silverleaf) [4] (push), with an attractive trap plant such as Napier grass (pull) planted as a border crop around this intercrop ...

    [2] [16] In sweet corn, reflective mulches can be an effective way to control D. maidis and the disease it vectors, compared to insecticides. [17] Mulching should be performed early in the plant's development to properly control this disease, as greater damage happens if the plant host is younger when infected with corn stunt disease.

  9. Southern corn leaf blight - Wikipedia

    Race T is infectious to corn plants with the Texas male sterile cytoplasm (cms-T maize) and this vulnerability was the cause of the United States SCLB epidemic of 1969-1970 [2] For this reason, Race T is of particular interest. While SCLB thrives in warm, damp climates, the disease can be found in many of the world's maize-growing areas. [3]
