General Information

Lucado is a sulfonylurea herbicide formulated with sulfosulfuron, a selective post-emergence herbicide effective against a broad spectrum of broadleaf weeds in various crops, including wheat, barley, rice, sugarcane, and maize. Sulfosulfuron is a highly active herbicide that inhibits the synthesis of branched-chain amino acids (BCAAs) in susceptible plants, leading to their growth arrest and eventual death.

Mode of Action

Sulfosulfuron works by interfering with the enzyme acetolactate synthase (ALS), a crucial enzyme involved in the biosynthesis of BCAAs, essential for plant growth and development. By inhibiting ALS, sulfosulfuron disrupts the BCAA synthesis pathway, leading to the accumulation of toxic metabolic intermediates and ultimately disrupting cellular processes.

Application and Usage

Lucado is typically applied as a post-emergence foliar spray, meaning it is applied to the foliage of weeds after they have emerged from the soil. The specific application timing and rate will vary depending on the crop, the target weeds, and the environmental conditions. Generally, Lucado is applied at a rate of 25 to 50 grams per hectare (1-2 ounces per acre).

Here are some additional factors to consider when determining the appropriate culture and dose:

• Crop growth stage: The growth stage of the crop can affect the effectiveness of certain cultures and doses. For example, some cultures may be more effective at controlling weeds early in the crop's development, while others may be more effective at promoting nutrient uptake later in the crop's growth cycle.
• Soil type: The soil type can affect the availability of nutrients and the effectiveness of certain cultures. For example, some cultures may be more effective in sandy soils, while others may be more effective in clay soils.
• Climate: The climate can affect the survival and activity of certain cultures. For example, some cultures may be more tolerant of drought or heat stress, while others may be more tolerant of cold or wet conditions.
• Desired outcome: The desired outcome of the application will also affect the culture and dose that is used. For example, if the goal is to increase crop yield, a different culture and dose may be used than if the goal is to control weeds.

Precautions and Safety

Lucado is classified as a moderately toxic herbicide (EPA Toxicity Category III). It is important to follow label instructions carefully and use personal protective equipment (PPE) when handling and applying Lucado. Avoid contact with eyes, skin, and clothing. Do not apply Lucado in windy conditions or when rain is expected within 24 hours of application.

Conclusion

Lucado is a versatile and effective herbicide for controlling a wide range of broadleaf weeds in various crops. Its selective action allows for targeted weed control without harming the desired crop plants. By effectively controlling broadleaf weeds, Lucado contributes to improved crop productivity and reduced yield losses. However, it is crucial to use Lucado responsibly, adhering to label instructions and safety precautions to minimize potential environmental impacts and protect human health.
