Fungal diseases cause great damage to agriculture. To combat them, fungicides with various active substances are used. Consider the scope and principle of action of propiconazole, its physico-chemical properties. What preparations used in agriculture and household plots contain this substance, how they are used. What precautions should be taken when working with the product.

Physical and chemical properties

Propiconazole belongs to the class of triazoles. It is the active ingredient in fungicides. Produced in the form of emulsion concentrate 9-25%. Preparations based on it are pesticides with systemic action, healing and protective preparations. Plants are treated by spraying.

Propiconazole is a colorless or yellowish viscous liquid, soluble in water and organic solvents, has a neutral acidity. Can be mixed with methanol, acetone and propanol. Solubility in 1 liter of water at 25 °C - 176.5 mg. Boils at 120°C, ignites at 250°C.

Use area

Preparations with propiconazole are used in agriculture to combat fungal diseases of cereals (wheat, barley, rye, oats), rapeseed, grapevine, black currant, red clover and essential oil rose. They have powerful activity against various types of spotting, rust, powdery mildew, as well as against septoria, rhynchosporia, cercosporellosis, phomosis, alternariosis, anthracnose, ascochitosis. Weakly inhibits root rot, fusarium.

Operation principle

Propiconazole inhibits the synthesis of ergosterol and the formation of spores, the development of fungi.The substance has a more toxic effect on their vegetative, rather than generative, organs. At the same time, it stimulates the growth of treated plants, enhances the flow of photosynthetic processes. In cereals, propiconazole does not move from the leaves to the ear, that is, it does not accumulate in the grain, the products remain clean, suitable for use in human nutrition and for processing into animal feed.

How to use

Propiconazole has a powerful healing effect on plants. On wet or cool days, its activity decreases, on warm days it increases. That is, spraying is recommended to be done in warm, dry weather. If after spraying the crops it rained, the effectiveness of the product does not decrease.The protective action lasts 3-5 weeks, allowing plants to develop without problems during this time.

On cereals from fungi, 1 treatment is carried out, the next spraying is done if the disease appeared early and had time to develop. The last treatment should be done one month before harvest.

Propiconazole can be combined in spray mixtures with most herbicides, foliar fertilizers, insecticides and growth regulators. The substance has no toxic effect on plants.

Precautions

In terms of toxicity, propiconazole belongs to the 3rd hazard class for humans and bees. After processing, at least 3 days must elapse before the start of mechanized work. The use of fungicides in the fishery zone is prohibited.

To work with the means you need to wear protective clothing, gloves, goggles and a respirator. If liquid gets into eyes, wash it off with clean water, remove from skin with soapy water.

If the fungicide solution has entered the stomach, you should drink activated charcoal at the rate of 6-7 tablets for a person of average weight, drink 1 liter of water. Then induce vomiting, stay warm and at rest, call a doctor. Treatment is symptomatic. If vapors are inhaled, move to fresh air, if symptoms of intoxication appear, call a doctor.

Propiconazole is an ingredient in many fungicides for use in household plots and agriculture. Provides protection to cereals, shrubs, grapes and other crops from fungi of various types. In addition to the fungicidal action, propiconazole has a stimulating effect on plant growth, enhancing photosynthesis processes.
