The soybean sowing campaign is almost complete. And even if you have initially provided this crop with proper soil protection, UKRAVIT experts remind you of the importance of using post-emergence herbicides – especially considering that the hydrothermal conditions of May promote the rapid emergence and growth of weeds. And the potential loss of future soybean yields due to excessive weeds can range from 30 to 80%.

As you know, soybeans have a fairly long herbocritical period – almost to flowering, when the rows begin to close, and during this period it is not able to compete with weeds for nutrients, moisture, space, and light – says the head of the agronomic department “UKRAVIT” Alexander Miglovets. – Therefore, effective herbicide protection is one of the keys to its full growth and development during this period and, accordingly, the formation of a high level of future yields. Therefore, in the conditions of the agro-season – 2021 for control of weed vegetation in soybean crops besides soil protection, it is necessary to apply effective insurance schemes. For fields with a high level of weeds such as quinoa, ragweed, datura, and others, I recommend choosing a mixture of drugsFlagship + Formula. Also for the destruction of a wide range of dicotyledonous and cereal weeds, including overgrown, you can use a combination of herbicidesFlagship + Imi-Wit».
The flagship herbicide based on bentazone has a contact effect and leads to an irreversible process of blocking the photosynthetic system, stopping the processes of cell division and growth and weed death. It controls a wide range of dicotyledonous weed species and is selective for the crop.
Herbicide Formula has a systemic effect. Thifensulfuron-methyl in its composition blocks the enzyme acetolactate synthase – a key enzyme of biosynthesis of essential amino acids (isoleucine, leucine, and valine). Inside the plant, the herbicide quickly moves to the places of greatest meristematic activity – growth points, as a result of which cell division, shoot growth, and weed root system stop. The drug destroys an extremely wide range of segetal vegetation, including some perennial species that germinate from seed, and is selective for culture. In addition, it has a low application rate and does not limit crop rotation.
Imi-Vit is a herbicide based on imazamox. This active substance enters the meristematic tissues or areas of growth by xylem and phloem, inhibits the synthesis of acetolactate synthase (ALS), an enzyme involved in the synthesis of essential amino acids – valine, leucine, isoleucine, necessary for protein synthesis and cell growth, and consequently to the death of weeds. The drug controls a wide range of annual dicotyledonous and cereal weeds. The action on weeds occurs both through the leaf surface and through the root system. In addition, due to the soil action, it has the ability to restrain the appearance of subsequent waves of weed seedlings (in the presence of soil moisture).
