Fungicide of systemic and contact action. Chemical class - benzimidazoles. Active ingredient: benomyl, 500 g of benomyl in 1 kg of the drug. It is produced in the form of a wetting white powder with a slight irritating odor - practically insoluble in water and most organic solvents. Not volatile. Hazard class for humans - 2 (highly toxic substance), for bees - 3-4 (moderately toxic substance). Producer: 'Agro-Kemi Kft', Hungary and CJSC 'August', Russia.
- The fungicidal effect is due to the cessation of the reproductive function of fungi, due to the violation of cell nucleus division, when the solution is absorbed through the roots, when processing seeds, applied to the stem or in the leaf axils.
- The therapeutic effect of the drug is manifested during the first three days, in the next 7 days the protective function remains.
- A little known fact, but benomyl (foundationazol) exhibits acaricidal action - it suppresses adult spider mites and their eggs. The insecticidal properties of foundationazol are in the suppression of aphids and leaf beetle larvae. This happens by restraining the transformation of the larvae into the adult stage (imago), but does not affect the eggs, a weakly toxic effect on the whitefly eggs. Presumably benomyl also has nematicidal properties.
- Fundazol does not possess phytotoxicity, but when applied to the soil in high doses, a toxic effect is manifested (inhibits plants).
- The fungicide is effective over a wide temperature range and can be used in early spring or late autumn.
- Can be mixed with other drugs that have a neutral aqueous solution - mixing with lime and alkaline solutions is unacceptable.
Fundazole is effective against pathogens of fungal infections, such as:
common and snow pine trees, moldy seeds, infectious lodging of conifer seedlings, powdery mildew, gray rot - the causative agent of the genus Botrytis, spotted pathogens of the genus Septoria, Cladosponum, Colletotrichum, wilting and Marssom pathogens of the genus Fusarium, Verticillium, Phialiphora, Cylindrocarpon, Rhistoctonia, Sclerotinia, etc.;
- Powdery mildew - 3 treatments, Root and bulbous rot, gray rot - 2 treatments, Spotted - 2-4 treatments, Seed pickling, seed mold - once, Fusarium - 2 treatments.
Features of the foundation
The active substance of the basezol moves in the vascular system of plants only in the acropetal direction: from bottom to top along the xylem and does not move along the phloem. Those. the systemic effect is manifested only during watering and absorption by the roots, as well as during seed treatment. When spraying, fungicidal properties appear only at the site of absorption - it does not move from one leaf to another in fungicidal doses.
According to G.S. Gruzdeva (Chemical Protection of Plants, 1987), foundationazol is not effective against bacteria, at the same time, the Regulations for the Use of Pesticides in Agriculture of the Russian Federation indicate that foundationazol can be used against bacteriosis on vegetables, legumes and cereals. Who is right?
Fundazol gives rise to a lot of controversy among flower growers and especially those involved in growing indoor plants. Fundazol is especially popular among lovers of orchids and bulbs, due to its high efficiency against fungi. However, some consider the drug too toxic and inappropriate for use in the household. Rumor has it that the Fundazol sold in the store is a fake and a fake, that it has not been produced for a long time.
At the moment Fundazol is included in the list of pesticides published in the 'State Catalog of Pesticides and Agrochemicals Permitted for Use in the Russian Federation' as of July 04, 2014. The registration of the foundation ended on 12.2014. At the time of this writing (April 2015), foundazol is indeed sold in stores from old purchases, but the Ministry of Agriculture of the Russian Federation has not released a new catalog of approved pesticides. So the further fate of this drug is still unclear.
But it should be noted that, like any other pesticide, foundationol has its own limitations (frequency of treatments) and requires the implementation of traditional safety measures. With the systematic use of the same fungicide, including basezole (benomil), the resistance of fungal spores can increase 3–12 times. Therefore, if the drug did not help you, you should not consider it a fake.
And besides, the foundation is not effective against rust fungi, downy mildew and fungi of the genera Peronospora (peronosporosis), Prytophtora (late blight), Pthium (soft rot, black leg) - these phytoparasites have genetic cross-resistance. It should be noted that according to the personal opinion of forestry experts, Fundazol is no longer so effective in combating diseases of conifers, which are like a scourge for foresters.
Foundation consumption rates
Dressing before planting tuberous (potatoes and other vegetables) by spraying. To prepare a solution, 10 g of foundation is dissolved in 0.5 l of water - this volume is enough for 10 seed tubers.
Etching of gladioli and amaryllis bulbs - by immersing the bulbs for 3 hours in a solution: 10 g per 2 liters of water, garlic - for a day in a solution: 10 g per 0.5 liters of water.
Instructions for using the foundation for the treatment of powdery mildew and other diseases on indoor and garden plants: spraying during the growing season with 0.1% working solution. 10 g of foundation is diluted in 10 liters of water, while 1.5 liters of solution is consumed per 10 square meters. Spraying before flowering and after harvest in horticultural farms, or at the first sign of illness on indoor flowers.
Fundazol (benomyl) has low toxicity for bees and birds. Toxic to fish. Refers to highly toxic compounds for humans and warm-blooded animals for cutaneous, inhalation and oral toxicity. Prolonged contact causes dermatitis.
Security measures. When working with the drug, be sure to wear a respirator and gloves. It is advisable to dilute the working solution not in the apartment, but on the street. Avoid eye and skin contact with foundation. It is unacceptable to eat, drink and smoke. Wash hands and face thoroughly after handling.
First aid in case of poisoning: if the drug gets on the skin, wash off with plenty of water; in case of contact with eyes, rinse abundantly with running water; if it enters the digestive tract, drink 3-4 glasses of water, induce vomiting, take several tablets of activated carbon, seek urgent medical attention.
Conclusions on the feasibility of using the foundation
When our flowers fall ill, especially our beloved, rare varieties obtained after a long wait from other parts of our country, or from abroad, we are ready to douse and spray them with anything, just to save them. We think a little about the consequences, but in vain. It is worth weighing the pros and cons. If you are not a future mother, you do not have children in the house and no less valuable than plants, pets, patients with asthma or immune diseases of family members, then you can try to save plants dying from an unknown disease. It is impossible to pinpoint a fungal or bacterial infection on your flowers at home. The data on foundazol are contradictory, perhaps its effectiveness against bacteria is too negligible, and the resistance of pathogens of fungal diseases, on the contrary, is high, which means that the whole enterprise can be held like a lottery.
For completeness, it should be noted that pesticides are divided into hazard classes for a reason, the 2nd hazard class of the foundation means that it causes allergic reactions, is a probable carcinogen for humans and a strong teratogen (fetal anamaly) for animals, and has reproductive toxicity. In this case, the basezol is slowly destroyed in the soil, the half-life of metabolites is from 3 to 6 months.
