Herbicides are used on agricultural crops to protect against numerous types of weeds. Let's look at the action and purpose of the herbicide "Merlin," its composition, release form, and advantages. We'll also discuss the correct dosage and application instructions, as well as the herbicide's toxicity and compatibility with other pesticides, storage instructions, and possible substitutes.

Composition, release form and purpose

The herbicide "Merlin" is produced by the renowned company "Bayer." It is a water-soluble granule product sold in 0.5 kg packages. The active ingredient is isoxaflutole, at a concentration of 750 g per kg. "Merlin" soil herbicide is a systemic product with selective action.

The product is applied to corn crops before the crop emerges to control 1-year-old 2-lobed and perennial cereal weeds.

What weeds does it work on?

"Merlin" is effective against such weeds as ragweed, knotweed, mustard, fumitory, quinoa, white goosefoot, sow thistle, black nightshade, shepherd's purse, chamomile, wild radish, amaranth, millet, foxtail and others.

Operating principle

Weeds absorb the herbicide solution through their roots, but only partially through their leaves. Isoxaflutole disrupts the enzyme that regulates carotenoid synthesis. This causes chlorosis, which kills the weeds within 5-7 days.

Merlin is most effective when the soil is moist. It can control not only emerging weeds but also future weeds. Its effectiveness decreases in dry soil and hot weather. However, it returns to its original state after precipitation.

How long does the effect last?

The protective effect lasts for 6-8 weeks, practically the entire corn growing season, and a second treatment is not necessary. The manufacturer sets this period based on average soil moisture. If the soil moisture is higher, the protective period is shortened. To control weeds, it is necessary to cultivate the rows or apply a protective herbicide spray.

Advantages of the drug

Advantages of the herbicide "Merlin":

wide coverage of weed species;
controls the 2nd and subsequent waves of weeds;
works reliably in different weather conditions;
long protective period;
low consumption rate compared to similar products.

Disadvantages of the herbicide "Merlin": decreased effectiveness in dry soil, application only to one crop.

Calculation of consumption

The application rate for corn is 0.1-0.16 kg per hectare; spraying is carried out before emergence, using 200-400 liters per hectare.

How to prepare a working solution

To prepare the herbicide solution, pour one-third of the water required according to the instructions into a container. Add the granules, stir, and let them dissolve completely. Then, add water until the solution is full. If fertilizer needs to be added, add it only after the granules have dissolved.

The Merlin formulation – granules – and convenient packaging ensure safety during solution preparation, minimize contact with the herbicide, and facilitate precise dosing of the granules.

Instructions for use

To maximize the effectiveness of the soil herbicide "Merlin," it's important to prepare the soil. According to the instructions, it should be uniform, free of lumps larger than 3-5 cm in diameter. The corn seeds should also be level and evenly distributed throughout the soil.

Herbicide spraying should be done after crop sowing and before seed germination. A finely dispersed solution is applied to the soil surface, not incorporated into the soil.

The soil should not be loosened until the corn has formed 4-5 leaves. This restriction is necessary to maintain the herbicide "screen."

Precautionary measures

Merlin is quite toxic to humans, so working with it requires wearing protective clothing. This clothing should cover all parts of the body that could come into contact with the solution. Necessary protective equipment includes a respirator, goggles, and rubber gloves. While working with the product, do not smoke, drink, eat, or remove your respirator.

After spraying, wash your hands and face with soap. If the liquid comes into contact with your skin, rinse with clean water. If it gets into your eyes, rinse them immediately with plenty of water.

How toxic is it?

In terms of human toxicity, this product is classified as Class 2. Its use near water bodies is prohibited due to fish poisoning. Merlin is selective for corn, does not inhibit it, and does not stunt the growth of seedlings or young plants. Some negative effects may be observed on light soils under conditions such as prolonged moisture or shallow seeding of corn seeds. Plants may experience yellowing and curling of the lower foliage. Corn recovers within 1-2 weeks; the herbicide does not affect yield or grain quality.

Possible compatibility

Merlin can be combined with a wide range of corn protection products (for example, those containing chloroacetanilides). Before mixing, check the chemical compatibility of the products. To do this, mix a small amount of each product. If there is no reaction, proceed to mixing the combined spray solution. If any changes in the physical or chemical properties are noticeable, do not mix the products.

Storage terms and conditions

Merlin herbicide can be stored in dark, cool, and moderately lit warehouses for three years from the date of production. Granules must be kept in the manufacturer's packaging and tightly sealed. Do not store the product near food products, household products, pharmaceuticals, or livestock or pet feed. It is permissible to store the herbicide near fertilizers and agrochemicals.

Failure to comply with storage instructions will shorten the shelf life of the medication. The prepared solution can only be stored for 1 day; after that, use is not recommended. Therefore, prepare only the amount you plan to use within 1 day.

Analogues

Merlin Flex and Adengo are similar products to Merlin in terms of isoxaflutole. They are available as emulsifiable concentrates and are also used to treat corn weeds.

The Merlin herbicide has proven itself in agriculture as an effective pre-emergent product, easily controlling many types of weeds, including noxious ones. Its use in agriculture is cost-effective because it requires only a small application rate and is economical. Using the herbicide helps reduce the cost of purchasing other products, making their use unnecessary. It does not affect the quality of the harvested corn grain.
