Sorotan sekilas
Clethodim adalah herbisida selektif golongan inhibitor ACCase (HRAC Grup 1) berbentuk cairan kuning-cokelat, larut dalam pelarut organik namun hampir tidak larut dalam air. Efektif mengendalikan gulma rumput tahunan dan perennial—seperti foxtail, crabgrass, dan quackgrass—pada tanaman dikotil (kedelai, sawi, kapas, sayuran) tanpa merusak tanaman inang. Bekerja secara sistemik pasca-aplikasi daun, dengan efek cepat (1–3 hari) dan desikasi lengkap dalam 7–14 hari, tanpa residu di tanah. Stabil pada pH 5–9, sensitif terhadap cahaya kuat dan kondisi ekstrem. Aplikasi optimal pada gulma fase 2–6 daun, suhu 15–28°C, kelembaban >60%. Mendukung pertanian berkelanjutan melalui pengurangan erosi, emisi karbon, dan penggunaan tenaga kerja hingga 50%.

3.Critical Factors
3.1 Factors Affecting Efficacy
3.1a Application Timing
Optimal efficacy occurs when weeds are in active growth phase (2-6 leaf stage), early application (2-3 leaf stage) is particularly important for certain difficult to control weeds.
3.1b Environmental conditions
-
Temperature
Optimal effectiveness between 15-28°C, reduced efficacy below 10°C or above 32°C.
-
Humidity
Relative humidity greater than 60% facilitates herbicide absorption.
-
Soil Moisture
Weed sensitivity to herbicide decreases under drought stress.
3.1c Dosage Control
Application rates should be adjusted according to weed species, growth stage, and density, generally ranging from 60-120g.
3.1d Application Technique
-
Spray Volume
Typically 200-300 L/ha, ensuring thorough coverage.
-
Nozzle Selection
Flat fan or cone nozzles provide better results.
-
Pressure Control
Medium pressure (2-3 bar) provides optimal spray quality.
3.1e Adjuvant Addition
-
Addition of specialized mineral oil or vegetable oil adjuvants (typically 0.5%-1% of spray concentration) significantly enhances efficacy.
-
Addition of water conditioners such as ammonium sulfate in hard water areas
3.1f Tank-Mix Compatibility
-
Good compatibility with most broadleaf herbicides and insecticides.
-
Efficacy may be reduced when mixed with certain foliar fertilizers and plant growth regulators.
-
Avoid mixing with pesticides containing phosphate components.
3.2 Management Considerations
3.2a Resistance Management
-
As an ACCase inhibitor (HRAC Group 1), should be incorporated into rotation plans.
