Soil herbicides are used in agriculture to treat fields before planting crops. They help control weed emergence. Let's look at the composition and action of the herbicide "Gambit," including its purpose, speed of action, advantages and disadvantages, and application rates. We'll also discuss how to properly prepare the solution, its phytotoxicity level, compatibility with other herbicides, and alternatives.
Composition and purpose of the herbicide
Gambit's active ingredient is prometryn, applied at a rate of 500 g per liter. This systemic herbicide is selective in its action. Crops treated include carrots, legumes, potatoes, corn, and sunflowers.
Existing forms of release
"Gambit" is produced by the company "August"; it is a suspension concentrate that is released in 5 and 10 liter canisters.
What plants does it affect?
It is used to destroy 1-year-old 2-lobed weeds and weed species of the cereal family.
Mode of action and how quickly it works
Prometrin penetrates weed tissue through the roots, partially through the leaves and stems, and also through seedlings. It inhibits respiration and photosynthetic processes and halts enzymatic activity. Weeds are destroyed upon germination or, if applied post-emergence, within 7-10 days.
How long does the protection last?
Depending on the weather 10-12 weeks.
Pros and cons
Calculation of consumption
Application rate of the herbicide "Gambit" (in liters per hectare):
- carrots – 1-1.5;
- legumes – 2.5-3;
- potatoes, corn, sunflower – 2-3.5.
The recommended application rate is 100-300 liters per hectare, with a waiting period of 2 months. The recommended frequency of treatments is 1.
How to prepare a working solution and the rules for its use
The instructions for use state that weather affects the product's effectiveness. In cold weather, it decreases, and the higher the temperature, the more active the herbicide is. If the product is applied before emergence, soil moisture also affects its effectiveness. In dry soil, the solution should be worked into the solution to a depth of 3-5 cm, while in moderately moist soil, it should be worked into the solution to a depth of 2-3 cm. The effectiveness of Gambit herbicide is reduced in wet and cold soil.
The Gambit solution should be prepared according to standard guidelines: pour a third of the tank's volume of water, add the solution, and stir. Add the remaining water and stir again.
Precautionary measures
Gambit is classified as a Class 3 toxicity product for insects and humans. It should not be used near bodies of water due to the risk of fish poisoning.
When working with herbicides, wear only appropriate clothing. The material should cover your entire body to prevent splashes. You should also wear goggles and a respirator. Do not eat or drink while working. Do not remove protective equipment. Keep all bystanders away from the area being treated.
After spraying, wash your face and hands. If the solution comes into contact with skin, eyes, or mouth, rinse with water. If symptoms of Gambit poisoning occur, take several charcoal tablets and drink plenty of water. If signs of serious poisoning occur, seek medical attention immediately.
Degree of phytotoxicity
Gambit herbicide is nontoxic to crops when used at the manufacturer's recommended doses. If used in excess, signs of crop suppression may appear, but these disappear within 1.5-2 weeks. It does not accumulate in the soil.
It decomposes in the soil by the next season and does not have a negative impact on the plants that will be planted next season.
Is there resistance?
To prevent weeds from developing resistance to the substance in Gambit, it should be alternated with other pesticides that contain compounds from other chemical classes.
Possible compatibility
Gambit can be combined with tank-mix pesticides and many soil-applied herbicides. However, before using a combined solution, it's important to check for compatibility. To do this, conduct a test: combine a small amount of both herbicides and check for a reaction. If the substances don't react, you can prepare a combined solution. If a reaction occurs, you need to choose a different one.
How to store it correctly and for how long
When stored properly, Gambit remains effective for 3 years. Storage conditions include low-humidity, dimly lit warehouses. Temperature: -5°C to +35°C. Store the product in its original packaging with the lid closed. The storage area should be free of food, feed, and medications. Pesticides and fertilizers may be stored in the same area.
After the expiration date, do not use the product due to decreased effectiveness. Store the prepared solution for only 24 hours. Discard any remaining solution on unusable soil. To avoid wasting the product, dilute only the amount needed for a working day's treatment.
Similar means
Gambit substitutes are products containing prometryn. These are herbicides for agricultural use: Alpha-Prometryn, Brig, Gezagard, Gezadar, Gonor, Gordon, Kraterra, Pozitiv Plus, Promex, Promenade, Promet, Prometryn, Sarmat, Fortis, and Shansgard. Due to the same ingredient, these pesticides have similar effects and kill similar plants. They can be used as a substitute for the main product if needed.
Gambit is a single-component soil herbicide that prevents the growth of many types of weeds. It can be applied before, during, or after sowing. It acts quickly, and its liquid form makes it easy to use. It does not cause weed tolerance and is economical to use. It is compatible with various pesticides, so it can be used in conjunction with them. It is non-phytotoxic and does not accumulate in the soil.
