Поєднання піроксасульфону + флуміоксазину

Pyroxasulfone: A Key Pre-Emergent Herbicide

What is Pyroxasulfone?

Піроксасульфон це soil-applied pre-emergent herbicide widely used in row crops like кукурудза, сої та  бавовна. This herbicide is effective against a range of annual grasses and some broadleaf weeds, providing long-lasting, residual control.

Механізм дії піроксасульфону

Pyroxasulfone inhibits very-long-chain fatty acid (VLCFA) synthesis, disrupting cell membrane formation in weed seedlings. This action prevents weed growth, making pyroxasulfone particularly effective in controlling лисиця, barnyardgrass та  свинячий. Its absorption through roots also ensures early-stage weed control, keeping fields clean during the critical growth phases of the crop.

Benefits of Using Pyroxasulfone

• Розширений залишковий контроль: Offers weeks of protection, minimizing the need for additional applications.
• Управління опором: Pyroxasulfone provides an alternative mode of action, especially beneficial in managing glyphosate-resistant weed species.
• Selective Action on Crops: Effective in protecting crops like кукурудза, сої, пшениця та бавовна with minimal risk of crop damage.

Pyroxasulfone has become a favored solution in Північна Америка та Австралія due to its effectiveness in areas where weed resistance is a significant concern.

Flumioxazin: Quick-Knockdown Herbicide for Broadleaf Weeds

What is Flumioxazin?

Flumioxazin is another powerful pre-emergent and post-emergent herbicide that is widely effective against широколистяні бур'яни. Known for its rapid action, flumioxazin is used in crops like сої, арахіс та виноградники to manage weeds such as водяна конопля, свинячий та lambsquarters.

Flumioxazin Mode of Action

Flumioxazin acts as a Інгібітор ППО (protoporphyrinogen oxidase), disrupting chlorophyll synthesis and causing oxidative damage in weed cells. This results in quick desiccation of target weeds, making flumioxazin ideal for fast weed suppression. Its action both on the leaf surface and in the soil allows for flexibility in pre- and post-emergent applications.

Benefits of Using Flumioxazin

• Rapid Weed Knockdown: Provides fast results, often within hours of application.
• Універсальне використання: Can be applied both before and after weed emergence, adapting to diverse weed control needs.
• Широкий спектр: Effective on a variety of broadleaf weeds, supporting clean fields throughout the growing season.

Flumioxazin’s effectiveness makes it a popular choice in regions where early-season weed control is essential for crop health.

Combining Pyroxasulfone and Flumioxazin: Enhanced Weed Control

Поєднання pyroxasulfone + flumioxazin offers a unique, dual-action approach for pre-emergent weed control. This mixture delivers the long-lasting residual benefits of pyroxasulfone along with the fast action of flumioxazin, making it a powerful solution for managing tough, resistant weeds.

Benefits of the Pyroxasulfone + Flumioxazin Combination

1. Подвійний режим дії: By combining VLCFA inhibition (pyroxasulfone) with PPO inhibition (flumioxazin), this herbicide mixture effectively manages a wide range of weeds and reduces the risk of herbicide resistance.
2. Широкоспектральний контроль: This combination targets both однорічні трави та широколистяні бур'яни, including species resistant to other herbicides, such as водяна конопля, barnyardgrass та свинячий.
3. Extended Residual with Immediate Action: Pyroxasulfone’s long residual effect maintains weed control for several weeks, while flumioxazin’s rapid knockdown provides immediate suppression, ensuring fields are clean as crops begin to establish.
4. Зменшена частота застосування: The combined residual and contact action of this mixture can reduce the need for multiple applications, saving time and costs for growers.

Target Crops and Application

This combination is primarily used in просапні культури як кукурудза, сої, бавовна та арахіс, а також в Росії виноградники та сади where early-season weed control is critical. The pyroxasulfone + flumioxazin mix is usually applied передсходовий, creating a barrier in the soil to prevent weed seedling establishment.

Формули та використання

• Склади: Common formulations include suspension concentrates (SC) та water-dispersible granules (WDG), allowing for flexible application and compatibility with various spray equipment.
• Термін застосування: Ідеальний для pre-plant or pre-emergent applications, as this combination prepares fields for planting with minimal weed competition.
