Perennial weeds can thicken cultivated plants, which causes significant harm when growing them. To destroy them, herbicides with selective action are used. Let's consider the treatment of crops with Bisom-300, its composition and formulation, mechanism of action, purpose. What are the consumption rates for this drug and the method of use, safety precautions, can it be combined with other drugs, how should the product and its analogues be stored.
Active substance and formulation
“Bis-300” contains clopyralid as an active substance, of which 300 g is contained in a liter of the drug. The manufacturer, Agrushim LLC, produces this herbicide in the form of an aqueous solution. This is a systemic pesticide by the method of penetration and by the nature of its action - a product with a selective effect. The herbicide is available in plastic canisters that hold 5 liters of the substance.
Mechanism of action and speed of action
After spraying, the herbicide solution is absorbed into leaf tissues and transported to growth points and roots. Clopyralid is a plant hormone created artificially. Its action in a weed plant leads to disruption and cessation of growth processes and subsequent wilting.
First, chlorosis appears on the leaves; the growing points die off after 1-3 weeks. "Bis-300" actively works on growing weeds, destroying thistle at almost all stages of development. Clopyralid remains in the soil for a long time, so the drug has an effect on weeds throughout the growing season.
Purpose of the herbicide
"Bis-300" is used on grains (wheat, barley, corn), rapeseed, sugar beets, flax, strawberries and lawns against 2-lobed perennial weeds that belong to the Asteraceae family.
When used in the recommended dosage, it does not have a phytotoxic effect on crops.
Method of application and consumption rates
According to the instructions, grain crops are processed when they reach the stage of tillering, emerging into the tube, corn crops - when the plants produce 3-5 leaves, beet crops - 1-3 pairs of leaves, rapeseed crops - when they have 3-4 leaves, flax when it reaches "Christmas tree" stage, strawberries - after harvesting the berries.
Application rates for Bisa-300 (in l per hectare):
- wheat, barley – 0.16-0.5;
- beets – 0.3-0.5;
- corn – 0.5-1;
- rapeseed for seeds – 0.3-0.4;
- spring rape – 0.5-1;
- strawberries – 0.5-0.6;
- lawn – 0.16-0.66.
200-300 liters of solution are consumed per hectare. The waiting period is 2 months, 1 treatment is carried out with the product.
Safety precautions when using Bisa-300
The herbicide belongs to the products that are assigned toxicity class 3 (for bees and humans). Not allowed to be used near bodies of water. You need to dilute the solution and work with it in protective clothing. Be sure to wear gloves, a respirator and goggles to protect your hands, respiratory tract and eyes from accidental splashes. After completing work, wash your hands with soap.
Compatibility with other pesticides
"Bis-300" combines well with 2,4-D and 2M-4X and other herbicides that are recommended for use on grains. On sugar beets, they are used together with products that contain phenmedipham, metamitron, triflsulfuron-methyl, chloridazone, desmedipham.
In other cases, it is necessary to separately check the compatibility of pesticides with Bis-300.
Terms and conditions of storage
