HPM All Clear Herbicide - Paraquat Dichloride 24% SL Non-Selective Contact Weed Killer

HPM All Clear is a broad-spectrum, non-selective contact herbicide formulated with Paraquat Dichloride 24% SL (Soluble Liquid). It is designed to quickly control a wide range of annual and perennial grassy weeds as well as broadleaf weeds. The product works on contact with green plant tissue, disrupting the photosynthesis process and causing rapid drying and wilting of unwanted vegetation. Farmers typically notice visible results within hours of application, making it a fast and reliable solution for field clearance.

This herbicide is suitable for use in many crops including tea, potato, cotton, grape, rubber, sugarcane, sunflower, rice, wheat, maize, and apple. It is especially useful in conservation and no-till farming systems because it only controls the foliage parts of weeds while leaving the roots intact. This helps maintain soil structure and prevents erosion. HPM All Clear can be used as a post-emergence directed spray or pre-plant application in many crops. The soluble liquid formulation leaves no visible residue on the surface, ensuring clean produce.

Key Benefits

• Non-selective weed control: Kills all types of harmful weeds, including grasses and broadleaf weeds, in one application.
• Fast action: Penetrates weed foliage quickly and shows visible results within a few hours after spraying.
• Complete removal: Ensures effective clearance of unwanted vegetation from the field.
• Reduces labour costs: Eliminates the need for manual weeding, saving farmers time and effort.
• No soil residue: Becomes biologically inactive after contact with soil, making it safe for subsequent cropping.
• Soil-friendly for no-till farming: Controls only the foliage while keeping roots intact, helping prevent soil erosion and maintain soil structure.
• Flexible application: Can be used for pre-plant, post-emergence directed, and inter-row applications across multiple crops.

How It Works

HPM All Clear contains Paraquat Dichloride 24% SL, which belongs to the Bipyridylium chemical class. It is a contact herbicide, meaning it only acts on the parts of the plant it directly touches. When sprayed on weed foliage, the active ingredient is absorbed by the green plant tissue with some limited translocation in the xylem. Once inside the plant cells, it disrupts the photosynthesis process by producing superoxide radicals. These highly reactive molecules damage the cell membranes and cytoplasm of the weed, causing the plant tissue to break down rapidly. This leads to quick drying, wilting, and death of the exposed parts of the weed. Because it is a contact herbicide and does not move extensively within the plant, it works best when applied thoroughly to cover all weed foliage. The product becomes inactive upon contact with soil, which means it does not leave harmful residues in the ground and allows for safe planting of crops soon after application.

When to Use

HPM All Clear is most effective when applied to actively growing weeds at an early stage. For best results, spray when weeds are young and tender, as the herbicide works by contact with green foliage. Apply as a post-emergence treatment after weeds have emerged but before they become too mature or woody. The product can be used for pre-plant application to clear fields before sowing, or as a directed spray between crop rows (inter-row application) in established crops. Avoid spraying during rain or when strong winds are blowing, as this can reduce effectiveness and cause spray drift. Application during sunny conditions with good light helps the herbicide work faster, as it disrupts the photosynthesis process. For aquatic weed control, apply directly to emerged vegetation in water bodies as per the recommended dosage.

Step by Step Usage Instructions

1. Prepare protective gear: Wear gloves, goggles, a mask, and protective clothing before handling the product.
2. Measure the correct dose: Check the crop-wise dosage table above and measure the required amount of HPM All Clear.
3. Mix with water: Add the measured amount to clean water in a spray tank. For a standard knapsack sprayer (15 liters), use 100 ml of product. Stir or shake well to ensure uniform mixing.
4. Spray evenly: Apply the mixture directly onto weed foliage. Ensure thorough coverage of all green parts of the weeds for best results.
5. Avoid crop contact: For inter-row or directed applications, take care to prevent spray from contacting the leaves or stems of the main crop.
6. Clean equipment: After spraying, thoroughly wash all spray equipment with clean water. Do not dispose of wash water near water sources.
7. Post-application care: Do not allow children, pets, or livestock to enter the sprayed area until the spray has completely dried.

Precautions & Safety

• Wear protective gloves, goggles, a face mask, and protective clothing while handling and spraying the product.
• Do not eat, drink, or smoke while mixing or applying the herbicide.
• Avoid direct contact with skin and eyes. In case of contact, wash immediately with plenty of clean water.
• Do not inhale the spray mist. Use a suitable mask during application.
• Keep the product away from children, pets, and food or feed storage areas.
• Store in a cool, dry place away from direct sunlight and moisture.
• Avoid spray drift onto nearby crops, water bodies, or non-target areas.
• Triple rinse empty containers before disposal. Do not reuse containers for any other purpose.
• Wash hands, clothes, and equipment thoroughly after use.

Side Effects & Phytotoxicity

HPM All Clear is a non-selective herbicide and will damage or kill any green plant tissue it comes in contact with. It should not be sprayed directly on crop foliage. Use only as a directed spray between rows or before planting. The product becomes biologically inactive upon contact with soil, so there is no residual soil activity that could affect subsequent crops. However, care must be taken to avoid spray drift onto desirable plants. This product is classified with a Yellow toxicity label, indicating moderate toxicity. Handle with caution.

PHI / REI & Storage

• Pre-Harvest Interval (PHI): Maintain at least 7 days between last application and harvest.
• Storage: Store in a cool, dry place away from heat, moisture, and direct sunlight. Keep in original container with lid tightly closed.
• Shelf Life: Store away from food, feed, and water sources. Keep out of reach of children and unauthorized persons.
