MESOTRIONE 10 SC

INTRODUCTION: MESOTRIONE 10% SC is a suspension concentrate herbicide for dilution with water and application by medium-high volume spraying equipment, containing as follows: Mesotrione :10% w/v (100 g/litre) Mesotrione belongs to the triketone class of herbicides that inhibit the enzyme 4-hydroxyphenyl-pyruvate-dioxygenase (4-HPPD), an essential enzyme in the synthesis of carotenoids (which protect chlorophyll from decomposition by sunlight). Susceptible plants that do not rapidly detoxify the herbicide become white to translucent, followed by necrosis of meristematic tissue and plant death. Uptake is foliar and via the root, with both acropetal and basipetal translocation. Non-susceptible plants, e.g. maize, have a differential metabolism (to the 4-hydroxy derivative) and may also have a slower foliar uptake. Mesotrione can be used as both a pre- and post-emergence herbicide for selective contact and residual control of broadleaf weeds in maize. When used as a pre-emergent herbicide, mesotrione is absorbed by emerging seedlings and requires rainfall for activation. Mesotrione applied post-emergence is absorbed by the foliage.

USAGES: MESOTRIONE 10% SC can used for the control of broad-leaved weeds, such as Xanthium strumarium, Ambrosia trifida, Abutilon theophrasti, and Chenopodium, Amaranthus and Polygonum spp., and some grass weeds (including Digitaria sanguinalis), in maize. MESOTRIONE 10% SC can be applied pre- or post-emergence of either crop or weeds.
