August's new fungicide Libertador with a unique mechanism of action will help potato growers and vegetable growers protect their future crops from the most harmful disease.
GENERAL
Libertador is recommended for use to protect open ground potatoes and tomatoes from late blight. The fungicide contains cyazofamide, 160 g / l, is produced in a technological and convenient suspension concentrate form. Libertador consumption rate is 0,4-0,5 l / ha, its can be applied up to three times per season. On potatoes, the waiting period is only 3 days, on tomatoes - 10 days. The consumption rate of the working fluid is 200-400 l / ha. Libertador is compatible with other pesticides, except for preparations with a strongly alkaline or strongly acidic reaction.
ADVANTAGES
The main advantage of Libertador is its unique mechanism of action, different from other currently used drugs. The fungicide has a long-term protective translaminar effect, i.e. it penetrates the plant and is distributed in the growing tissues.
libertador manifests very high resistance to washout by precipitation and when using irrigation. Spraying with the drug can be started as early as two hours after watering, in addition, the fungicide does not reduce its effectiveness, even if it rained or watered shortly after treatment.
libertador immediately exhibits a protective and antisporulatory effect, stops the development of the disease (the so-called "stop effect"). That is, this drug is an ambulance in case of late blight epiphytoty. After all, it is effective against all stages of pathogen development, starting with the suppression of zoospores on the surface of the leaves and soil. This fungicide eliminates the possibility of infection of new crop tubers. This property is not found in many other "potato" fungicides.
The drug has long period of protection. Although Libertador is not systemic, it travels to developing tissues within seven days, providing culture protection for two to three weeks.
Due to the content of cyazofamide from the chemical class of cyanoimidazoles, which is not yet very widely used in potato growing, as well as the unique mechanism of action, Libertador is excellent component of anti-resistance and integrated protection systems potatoes and tomatoes. After all, it is effective against oomycetes resistant to drugs from other chemical classes. Fungicides with the same active ingredient are already used in European countries to control the development of resistance in the causative agent of late blight.
In addition, Libertador It is gentle on the crop and is safe for beneficial insects and mites.
HOW TO APPLY
Libertador is recommended to be used as part of two main defense strategies.
The first. Spraying during the period of stopping the active growth of tops and the onset of favorable conditions for the development of late blight. The main purpose of this strategy is to protect potatoes from infection during the period of tuber growth. Also, the drug can be used for pre-harvest spraying before desiccation or at the time of its implementation, which ensures maximum protection of new crop tubers from infection with late blight.
The second. Spraying at any time when an outbreak of late blight occurs. To do this, Libertador must be added to a systemic or translaminar drug (Inside, Metaxyl). This allows you to block the source of infection on the field.
In all cases, it is recommended to add the Polyphem adjuvant to the working solution of the drug, and prepare the water for the preparation of the working fluid using the Soylent conditioner.
