1. Prodiamine: Preventive Herbicide
Chemical properties and mechanism of action
Prodiamine belongs to Dinitroaniline Herbicides, which is a highly effective preventive herbicide. It prevents weed seed germination and root growth by inhibiting microtubule formation and interfering with cell division.
Timing of action: Prodiamine is designed to be applied pre-emergence to stop the growth of weed seeds as they begin to germinate.
Systemic: Prodiamine forms a chemical barrier in the soil and inhibits the early growth stages of weeds by contact action.
Targeted Weeds
Prodiamine is highly effective in inhibiting seed germination of a wide range of annual grass and broadleaf weeds, primarily:
Gramineous weeds: Crabgrass, Foxtail.
Broadleaf weeds: Ragweed, Clover.
Areas of application
Lawn Management: Used to prevent annual weed seeds from germinating and to ensure a clean and even lawn.
Farmland Management: Widely used for pre-emergence weed control in corn, cotton and other crop fields.
Landscape and non-cultivated land: suitable for long-lasting weed management in parks, flowerbeds and other areas.
Advantages
Long-lasting: Provides months of weed suppression.
Safe: Harmless to a wide range of turfgrass species and soil persistent.
Reduced number of applications: Long-term protection can be achieved with a single application.
2. Quinclorac: Persistent Weed Control in Lawns and Fields
Chemical Properties and Mechanism of Action
Quinclorac is a synthetic growth hormone herbicide that interferes with weed cell division and growth by mimicking natural plant hormones (auxins). It also inhibits cellulose synthesis and destabilizes weed cell walls.
Systemic action: absorbed through the leaves and delivered to the growth point of weeds, it controls weeds comprehensively from the inside to the outside.
Dual Function: Acts simultaneously on grass weeds and certain broadleaf weeds to provide multi-functional protection.
Recommended Reading: Fenoxaprop and Quinclorac
Targeted Weeds
Quinclorac demonstrates excellent control of the following weeds:
Grass weeds: Crabgrass, Foxtail.
Broadleaf weeds: Pigweed, Clover.
Areas of Application
Turf management: Focus on controlling mature weeds, especially Crabgrass.
Agricultural applications: Widely used in rice fields and areas requiring integrated weed management.
Advantages
Fast acting: weeds quickly stop growing and die back after application.
Durable: Provides long term weed suppression and reduces weed recurrence.
Broad Spectrum: Covers a wide range of grass weeds and some broadleaf weeds.
3. Prodiamine and Quinclorac blends
Scientific Basis for Mixing
The combination of Prodiamine and Quinclorac is a classic preventative and curative weed control program:
Prodiamine provides pre-emergence control, stopping weeds from emerging by inhibiting seed germination.
Quinclorac provides post-emergence control, quickly removing weeds that have already grown.
The advantage of this combination is that they work together to achieve full life cycle control of weed growth through completely different mechanisms of action.
Advantages of synergistic action
Comprehensive coverage of target weeds:
Grass weeds (cricket grass, dogwood).
Broadleaf weeds (ragweed, clover).
Combination of fast-acting and long-acting:
Quinclorac is responsible for the fast kill of existing weeds, ensuring significant short-term results.
Prodiamine provides a long-lasting soil barrier that inhibits the germination of future weed seeds.
Reduces weed recurrence:
The mix not only removes current weeds, but also prevents future weeds from growing, reducing the number of applications and improving cost-effectiveness.
Applicable Scenarios
Lawn Management: Use on golf courses, residential lawns and parks to ensure complete weed removal and long-term uniformity.
Agricultural applications: In corn, rice and other crop fields to provide integrated weed management over multiple seasons.
Non-cropland applications: in highway slopes and industrial areas to provide long-lasting protection.
4. Application recommendations for mixed formulations
Timing of application
Prodiamine: Apply prior to weed seed germination to create a soil barrier.
Quinclorac: Apply early in the weed’s growth (e.g., the 1-3 leaf stage of cricket grass) to ensure fast results.
Mixture Ratio and Application Method
Adjust the mix ratio of the two components according to the target weed type and density.
Use a sprayer to cover the target area evenly to avoid missing.
Precautions
Avoid application when soil is too dry or when weeds are not actively growing to ensure maximum effectiveness.
Prevent drift to non-target plants and protect neighboring crops or turfgrass species.
Ensure application areas are dry after spraying before allowing human or animal access.
5. Summary: A Comprehensive Integrated Weed Management Program
The combination of Prodiamine and Quinclorac provides a comprehensive, effective weed management solution. The synergistic action of prevention and treatment provides comprehensive control of grass and broadleaf weeds. This combination is ideal for weed management in both lawn care and agricultural applications, as it dramatically improves weed control efficiency while reducing the risk of weed recurrence.
