10-Node Cotton Plant<\/p><\/div>\n

When squares are missing on the plant and cotton fleahoppers are suspected to be the cause, count the number of nodes between the missing square and the pinhead sized square.<\/span>\u00a0 <\/span>If a node is added every 3 days and there are 4 nodes between the missing square and the pinhead square, the square was lost at least 12 days ago. This result is because a cotton fleahopper injures squares smaller than a pinhead.<\/span><\/p>\n

The first bloom on a plant usually occurs when the plant has 9 nodes above the first position white flower.<\/span>\u00a0 <\/span>To determine the time until bloom, count the number of nodes above the first square to the uppermost mainstem unfurled leaf (1-inch width).<\/span>\u00a0 <\/span>Subtract this from 9 and multiply by 3 and you have an approximate number of days until bloom. <\/span>\u00a0<\/span>If the plant has 10 nodes and the first square is on the 6<\/span>th<\/span><\/sup> node, there are 4 nodes above the first square.<\/span>\u00a0 <\/span>Subtract 4 from 9 and multiply difference (5) by 3. <\/span>\u00a0<\/span>There should be about 15 days to bloom.<\/span><\/p>\n

More information on how the plant grows can be found at the National Cotton Council website\u00a0HERE<\/a><\/span>.<\/span><\/p>\n
