Atticus Cavallo 4 SC Herbicide - Mesotrione 40% - 2.5 Gal (2/Cs)
About this product
Atticus Cavallo 4 SC is a selective systemic herbicide containing 40% mesotrione (four pounds of active ingredient per gallon) as a suspension concentrate. It provides both contact and residual control of broadleaf weeds and is taken up through leaves, shoots, and roots, which allows pre-emergence or post-emergence use. Its 4-HPPD-inhibitor mode of action controls weeds that are resistant to glyphosate, ALS-inhibiting, and triazine herbicides. EPA Registration No. 91234-75.
Active Ingredient
| Property | Value |
|---|---|
| Active ingredient | Mesotrione 40% |
| Formulation | Suspension concentrate (SC), 4 lb AI per gallon |
| Herbicide group | WSSA Group 27 (HPPD inhibitor, bleaching) |
| Action | Selective, systemic, contact and residual |
Mode of Action
Mesotrione inhibits the enzyme 4-hydroxyphenylpyruvate dioxygenase (4-HPPD), blocking the biosynthesis of carotenoid pigments. Without carotenoids to protect chlorophyll from light, susceptible weeds bleach white and then die. The product is absorbed through foliage on emerged weeds and through the soil by germinating weeds.
Weeds Controlled
Controls tough broadleaf weeds including velvetleaf, cocklebur, pigweed, sunflower, and nightshades. It does not control most grass weeds.
Crops and Application
Labeled for field corn, seed corn, popcorn, sweet corn, and other listed crops, with flexible pre-emergence and post-emergence timing. In pre-emergence use, weeds take up the product through the soil; at least 0.25 inch of activating rainfall within 7 to 10 days improves performance. In post-emergence use, susceptible weeds stop growing soon after treatment and can take up to two weeks to die. Temporary, transient bleaching may appear on field corn under stress or extreme weather and is outgrown without yield effect.
| Timing | Rate |
|---|---|
| Post-emergence (minimum) | 3.0 fl oz per acre |
| Maximum per year | 7.7 fl oz per acre (0.24 lb mesotrione AI per acre) |
When applied post-emergence following a mesotrione-containing pre-emergence herbicide on corn, add atrazine as a tank-mix partner.
Resistance Management
Use full labeled rates and rotate or tank-mix with herbicides of a different mode of action. If additional herbicide is needed, use a product other than another Group 27 (HPPD) inhibitor.
Safety and Handling
Wear a long-sleeved shirt, long pants, shoes, socks, gloves, and eye protection. Avoid spray drift, and clean application equipment thoroughly to prevent injury to sensitive crops sprayed afterward. Avoid contamination of water bodies.
