Biological products for protecting plants from fungal and other diseases are especially popular with gardeners due to their natural composition. Unlike products containing chemicals, they act more slowly, but they do not harm the soil and human health. The use of "Rizoplan" in personal plots and fields allows avoiding diseases such as root rot, vascular bacteriosis and powdery mildew.
The composition and form of release of the fungicide
Biological fungicide "Rizoplan" is produced on the basis of living cells of Pseudomonas fluorescens. These soil bacteria effectively destroy the causative agents of most fungal diseases affecting cultivated plants. Their concentration in the fungicide preparation is 1 billion CFU / ml.
The biological product is on sale in the form of a liquid solution, which must be diluted in water before use. Rizoplan is packaged in 5 liter plastic cans. The manufacturer of the biological product is the domestic company Biopesticides LLC.
When to use and how it works
The biological product is designed for pre-sowing treatment of seed material, seedling roots before planting soil and crops throughout the growing season. Thanks to live microorganisms, the agent effectively destroys pathogens such as mildew and powdery mildew in grapes, black leg and vascular bacteriosis in cabbage, clump rot in sugar beets, septoria and root rot in cereals, late blight in potatoes.
The preparation based on live bacteria is characterized not only by bactericidal and fungicidal effects, but also stimulates the growth of cultivated plants.
The instructions for use indicate in which cases it is advisable to use Rizoplan:
- dressing and preparation for planting seed material of grain and vegetable crops;
- treatment of potato tubers before planting in the ground;
- root irrigation of plants throughout the growing season;
- processing of soil and greenhouse structures after harvest;
- irrigation of indoor ornamental plants.
After getting into the tissues of a cultivated plant, the biofungicide begins to have a depressing effect on pathogenic microorganisms, which leads to their death.
The gardeners attributed the following points to the advantages of Rizoplan:
- increases the productivity of cereals and vegetables by 10%;
- stimulates plant immunity and resistance to adverse weather conditions;
- increases the protein content in grain up to 20% and improves its quality;
- used at any stage of the growing season of crops;
- contributes to the saturation of the soil with beneficial microorganisms and restores fertility;
- does not lead to the development of resistance, therefore, the fungicide can be used for several seasons in a row;
- it is used in tank mixtures with almost all chemicals, with the exception of products containing mercury;
- contributes to the production of environmentally friendly vegetables.

In the instructions, the manufacturer indicated the consumption rates of the biofungicide, which must be adhered to during the use of the product.
Consumption of "Rizoplan" for different cultivated plants is indicated in the table:
|Cultivated plant||Diseases against which the drug is used||Biofungicide consumption rate||Working solution consumption|
|Sugar beet||Powdery mildew and downy mildew||2 liters per hectare of planting||300 liters, treated 1-2 times throughout the growing season|
|Spring barley||Root and fusarium rot, rhynchosporium, seed mold||0.5 to 1 liter||For processing crops, take 20 liters per hectare, for soaking seed material before planting - 10 liters per ton|
|Potatoes||Late blight and macrosporiosis||1 liter||To process a ton of tubers before planting in the ground, use 10 liters of solution|
|Grapes||Oidium and mildew||4 liters per hectare of plantation||Grapes are processed up to 4 times during the growing season, using 800 to 1000 liters of liquid per hectare|
|Apple trees||Moniliosis and scab||5 liters||4-fold treatment per season, you will need from 800 to 1000 liters of working fluid|
|Cabbage||Vascular bacteriosis and black leg||2 liters||Cultivated 2-3 times during the growing season, using from 300 to 400 liters per hectare of field|
|Strawberry||Gray rot||4 liters||2x processing using 300 liters of working solution|
Biofungicide does not have a waiting period after treatment, therefore, if necessary, you can harvest a few days after application of the product.
The spray solution should be prepared just before using the fungicide so that it does not lose its effectiveness. First, the amount of the drug indicated in the instructions is dissolved in a small amount of water (2-3 liters), after which the mother liquor is poured into the sprayer tank, half filled with water, and the mixer is turned on. After acquiring a solution of a homogeneous consistency, add the remaining water and mix again.
The solution remaining after processing must be disposed of in accordance with safety requirements. It is recommended to spray plants in clear weather, with a minimum wind speed, in the morning or evening.
Precautions when working with the drug
Biofungicidal preparation "Rizoplan" belongs to the 4th class of toxicity for humans, warm-blooded animals and insects. However, when working with it, you must follow simple safety rules. Use protective clothing and gloves, as well as a mask during processing.
At the end of spraying the plants, they thoroughly wash the entire tool, wash clothes and take a shower with soap. If drops of solution get on the skin or mucous membranes, wash them with plenty of water.
What is it compatible with?
