Modern agrochemicals offer farmers a wide range of weed control products. Some are designed to kill pests in vegetable fields, while others protect grain crops. The herbicide "Octapon Extra" kills annual and some perennial broadleaf weeds, making it a popular and effective crop protection product.
Composition, dosage form and purpose
Octapone Extra is a systemic pesticide belonging to the aryloxyalkanecarboxylic acid class. It is available as a concentrated emulsion. The active ingredient of the herbicide is 2-4D (2-ethylhexyl ether) at a concentration of 500 grams per liter.
This product is designed to protect grain crops from various types of weeds (sow thistle, field bindweed, field mustard, and field thistle). It is used on wheat, rye, barley, and corn.
Octapone Extra is packaged in 20- and 30-liter plastic canisters, mounted on pallets for easy transportation. The herbicide containers are tightly sealed with lids, and labeled with information about the manufacturer, product name, ingredients, and intended use.
Mechanism of action
The product has both contact and systemic action. Penetrating the weed through the leaves and spreading along the stems and roots, the herbicide accumulates in the tissue and destroys cells. This stops the weed's growth, parts of the plant begin to wither, and the weed dies within two weeks.
Pros and cons
Every agrochemical has its advantages and disadvantages. The advantages of Octapon Extra include:
- economical use of the product with high efficiency;
- no impact on crop rotation;
- rapid penetration into the weed, the onset of action 1.5-2 hours after treatment;
- The product does not wash off in rain within an hour after application.
The herbicide is used in temperatures ranging from +5 to +25°C. It destroys root suckers. Its disadvantages include its high cost and the potential for weed resistance.
Calculation of consumption
Do not exceed the herbicide application rate recommended by the manufacturer.
| Cereals | Concentrate consumption, in liters/hectare | Spraying period |
| Barley, rye, winter and spring wheat | 0.6-0.8 | Winter crops are sprayed in early spring, spring crops - during the tillering period of crops |
| Corn | 0.6-0.8 | Spray when 3-5 leaves appear. |
| Forage grasses | 0.6-0.75 | When 2-3 leaves appear |
