The first step in controlling morningglories is identification. Entireleaf morningglory and pitted morningglory are generally the two species we find in peanut fields. Ultra Blazer, Storm, and Cobra can be weak on entireleaf morningglory because of the pubescence (hairs) on the leaves that minimize coverage on the leaf and absorption of herbicides. These herbicides do a great job on pitted morningglory (smooth leaves with few hairs.) 2,4-DB is very good on entireleaf morningglory but offers almost no control of pitted morningglory. In many fields, a mixture of a PPO herbicide and 2,4-DB offers control of all morningglories. Cadre is also very good on all morningglories we have, and you will get residual control of the next flush wth Cadre. Paraquat is good on morningglories but they need to be small. Anthem Flex adds to control of morningglories. Basagran also has activity on morningglories.
