Violations from year to year of grain growing technology and non-compliance with crop rotation lead to the accumulation of weed seeds in the soil and, as a consequence, to a significant increase in weed infestation, say experts UKRAVIT SCIENCE PARK.

Excessive weed infestation poses a particular threat to winter cereals in the autumn: at this time the basis for future yields is laid, and any competition from segetal vegetation can have an extremely negative impact on the further growth and development of crops.
“Autumn herbicide treatment is an important element of the technology of growing winter grain crops, especially early sowing dates,” said Oleksandr Myhlovets, head of the company’s agronomic department. – First, it eliminates competition from weeds for vital resources in the early stages of grain growth, and secondly – removes the problem of wintering and winter weeds, which are especially difficult to control in the spring. Third, in autumn weeds are more sensitive to the action of herbicides phases, and therefore, the effectiveness of such treatment will be clearly higher. Finally, treatment during this period is less dependent on adverse weather conditions, which often occur in the spring and complicate timely spraying. In addition,
For autumn herbicide spraying of winter grain crops, Alexander recommends choosing a tank mix of drugs Panda (pendimethalin, 330 g / l) + Gold Star (tribenuron-methyl, 750 g / kg). This combination perfectly controls a wide range of dicotyledonous, including resistance to 2.4 D, and some cereal weeds.
Panda is a systemic herbicide. It reliably and long-term controls a wide range of annual dicotyledonous and cereal weeds. The active substance – pendimethalin penetrates the weeds through the primary root system and seedlings and inhibits cell division and growth. Weed-sensitive weeds die immediately after seed germination or after emergence. Due to its physicochemical properties, pendimethalin has low solubility in water and a low level of mobility in the soil, so it does not leach into the lower horizons and does not cause phytotoxicity.
Gold Star is a highly effective systemic herbicide. Tiburon-methyl in its composition blocks the enzyme acetolactate synthase – a key enzyme in the biosynthesis of essential amino acids (such as isoleucine, leucine, and valine). Inside the plant, the active substance quickly moves to the places of greatest meristematic activity – growth points, stopping cell division, shoot growth, and weed root system. Tiburon-methyl effectively destroys difficult-to-control dicotyledonous weeds in the early stages of grain growth (starting from the 2nd leaf) and is the optimal lateral “partner” for pendimethalin, which effectively restrains the waves of autumn weed seedlings due to soil action. The tank mix will provide reliable protection of crops during the whole autumn period, will promote optimum overwintering and fast restoration of vegetation in the spring.
