sunflower cultivation allows to achieve good results in this branch of agricultural production. This includes seed processing, soil preparation, and compliance with crop rotation rules, as well as timely care of the crop and providing it with optimal growing conditions. An important component of this process is weed control. For maximum efficiency, the Swiss company Syngenta offers a powerful product capable of providing complete protection of sunflowers from most weeds - Captor herbicide.
Characteristics of the drug

Captora herbicide is an excellent tool for sunflower protection, able to cope with an incredibly wide list of weeds in crops. These are monocotyledonous, including cereal, and dicotyledonous weedy competing plants. It will be more effective to use TM Clearfield or other sunflower varieties and hybrids resistant to this herbicide. The product is convenient to use, as there is a sufficiently wide window for culture processing. According to the manufacturer's recommendations, the maximum effect of protection with minimal risks of damage to the crop will be achieved with a single treatment in the phase of 4-5 true sunflower leaves and no more than 2-3 weed leaves. The active ingredients imazamox and imazapyr from the class of imidazolinones create a protective screen on the soil in a certain way. It provides maximum long-term control of annual and some perennial weeds that germinate from seeds. At the same time, during almost the entire vegetative period of the culture, the following stages of weed formation are also suppressed (a peculiar control of the wave-like appearance of germination is carried out), which is in itself extremely beneficial for farmers. Absorption of the product by the leaves and root system of the plant in some cases, after a few hours, contributes to the appearance of the first signs of the beginning of the death of the weed. Captora herbicide is one of the most effective means in the fight against such a weed-parasite as the blight, which is a serious and rather late type of pest.
Instructions for use of Kaptor herbicide
The recommended dose of the drug is 1.0-1.2 liters per 1 ha of fields. At the same time, the consumption of the working solution is 200-400 liters. In situations where there are large remnants of vegetation on the ground, the total amount of working fluid should be at least 250 liters. The solution itself must be prepared on the day of treatment. The absence of mechanical treatment of the rows for 10-14 days after the application of the herbicide will provide protection against perennial rhizome weeds. For maximum herbicidal action, sunflower is best processed at a temperature of 14 °C to 25 °C above zero. Spraying is best done in the morning or evening, in windless and dry weather. If precipitation is predicted, then it is necessary to calculate the processing time so that after it there is no rain for 2 hours. Since the Kaptor herbicide is a powerful and highly effective drug, its combination in tank mixtures with other SSRs for weed control or mineral

insecticides| ||154 запрещено. Также не рекомендуется применять препарат, если выращиваемая культура находится в состоянии стресса (по причине засухи, низких или наоборот чрезмерно высоких температур, повышенной влажности). Так как возможно кратковременное негативное влияние на подсолнечник в виде изменения цвета или уменьшение роста, которое самостоятельно проходит через 1-2 недели. Определенные рекомендации следует придерживаться и при организации севооборота. Без ограничений допускается выращивание устойчивых к действующему веществу специальных сортов подсолнечника, кукурузы, рапса. Спустя четыре месяца возможен посев пшеницы и ржи, девять месяцев – ячменя, люцерны, сои, овса, кукурузы и гороха. Картофель, томаты и другие овощные культуры можно высевать через 19 месяцев, а обычный рапс, сахарную и другие свеклы не ранее 26. Гербицид Каптора рациональней использовать не чаще 1 раза в три года на одном участке.
