I. Product Profile
Isopropyl 50% Wettable Powder is aSelective pre-emergence and early post-emergence herbicides, which belongs to the class of substituted urea herbicides. This product hasSystemic activityIt is primarily absorbed through plant roots, though stems and leaves can also absorb it. It is transported upward with water to the leaves, where it inhibits photosynthesis in weeds, causing them to starve to death because they are unable to synthesize organic matter. It is primarily used to control annual grass weeds and certain broadleaf weeds in winter wheat fields and is a classic product for weed management in wheat fields.
II. Mechanisms of action of active ingredients
Target: Photosynthesis inhibitor (PSII inhibitor)
Ipropamol belongs toHRAC Class C1 / WSSA Class 7Herbicides with a mechanism of action:
forms
| active link | Specific mechanisms |
|---|---|
| absorption pathway | Mainly throughAbsorption by Plant Roots...the stems and leaves can also absorb it, and it is transported upward with water to the leaves |
| biochemical target | Inhibition of QB proteins in the photosynthetic electron transport chain, blocking the transfer of electrons from QA to QB |
| physiological effect | Inhibits photosynthesis in weeds, preventing the synthesis of organic compounds (ATP and NADPH) |
| final performance | Weeds gradually turn yellow, wither, and die due to ”starvation.” |

-
Soil moisture at an appropriate level helps improve the effectiveness of pest control.
-
Weed control is more effective when the soil is moist at the time of application.
III. Product characteristics
✅ Six Core Advantages
forms
| Specificities | particular |
|---|---|
| 🎯 Pre- and post-budding: dual benefits | Combines soil-incorporated and foliar activity, with a wide application window |
| 🔄 Systemic action, thoroughly eradicates | After being absorbed by the roots, it is transported to the leaves, destroying the weeds from the inside out, with no regrowth. |
| ⏱️ Broad-spectrum weed control; effectively eliminates both grass and broadleaf weeds | It is effective against both annual grass weeds and certain broadleaf weeds. |
| 🛡️ Safe for wheat, highly selective | It is safe for winter wheat at the recommended dosage and does not affect yield. |
| 💧 Flexible and versatile | Can be applied as a soil treatment before emergence or as a post-emergence foliar spray |
| 🌾 Excellent compatibility and flexible options | Can be mixed with 2,4-D, methyldisulfuron, diquat, and diflusulfuron to broaden the spectrum of weed control |
🎯 Preventing Objects
Primary prevention and eradication: Annual grass weeds such as wild wheatgrass, early ryegrass, hard grass, crabgrass, wild oats, chickweed, small amaranth, cress, mustard, rye grass, chamomile, cow parsley, and amaranth, as well as some broadleaf weeds.
Suitable crops: Winter wheat.
IV. Usage and dosage
📋 Application Guidelines for Winter Wheat Fields
forms
| Application period | Dosage (formulated dose/acre) | water consumption | Mode of application |
|---|---|---|---|
| post-sowing before seedling | 100–125 grams per mu | 30-40 kg/mu | Soil spraying |
| From the two-leaf-one-heart stage of wheat seedlings until just before the jointing stage(Weeds at the 2–5-leaf stage) | 100–125 grams per mu | 30-40 kg/mu | Foliar spray |
Active ingredient dosage: The application rate of the active ingredient per mu is 50–62.5 grams per mu. Applying the pesticide when soil moisture levels are appropriate helps improve its effectiveness.
V. Guidance for use
🔧 Application Points
forms
| move | operational specification |
|---|---|
| 1. Seize the opportunity | Apply the herbicide after seeding but before seedling emergence, or after wheat seedlings have developed two leaves and one node but before the jointing stage, when weeds are in the 2–5-leaf stage. |
| 2. Method of Dosing | Using the two-step dilution method, first dilute with a small amount of water until dissolved, then add sufficient water. |
| 3. Spray evenly | Mix 30–40 kilograms of the product with water per mu and spray evenly; avoid over-spraying or missing any areas. |
| 4. Soil Moisture | Weed control is more effective when the soil is moist at the time of application. |
⚠️ Key Considerations
-
⏰ Optimal application period: Winter WheatFrom the two-leaf-one-heart stage to just before the jointing stage, weeds2–5-leaf stageThis provides the best results.
-
🌡️ Things to Avoid During a Cold Snap: When taking medication, pay attention to the weather forecast,Do not apply pesticides during frosts or cold snaps.Otherwise, the wheat is susceptible to frost damage and pesticide damage. Generally, pesticides should be applied during a period of high temperatures after sowing or after the first cold snap has passed.
-
🚫 Prohibited plots: Land treated with superphosphate, fields with weak crop growth or frost damage, areas where tilling was incomplete, andSoil with a high sand content or poor drainageThis product should not be used.
-
💧 Mixing Requirements: Stir or shake the sprayer continuously while spraying to prevent the solution from settling.
-
🐟 Aquatic safety: Apply the pesticide away from aquaculture areas, and do not wash application equipment in water bodies such as rivers or ponds.
