Chemicals under the general name of fungicides are widely used in agriculture, farming, and horticulture. They are pesticides designed to kill fungus. This helps to prevent the emergence and development of diseases dangerous to plants. These funds are used not only to combat already developed diseases. They are also used for prevention purposes. They have proven to be effective chemicals against infections, fungi and pests.
Overview
Don't be intimidated by the terms "fungicides" and «pesticides». Nowadays, the latter has received a negative connotation. Although in fact, these chemicals are of great benefit. They prevent the development of pathogenic bacteria and pest attacks. In combination with all kinds of fertilizers and additives, such formulas allow you to increase the yield and improve its quality. The fruits are getting bigger. Their shelf life is increased.
The drugs are available in different forms. It could be:
The drugs are available in different forms. It could be:
- fluid;
- powder;
- granules;
- suspension;
- emulsion;
- paste;
- spray;
- solution.
Substances have different purposes and a wide range of activities. They allow you to fight rot, powdery mildew, fusarium, late blight and other diseases. Separate formulas are designed to strengthen the immune system to fight these lesions.
Fungicides are produced for different crops:
Fungicides are produced for different crops:
- for orchids;
- for roses;
- for indoor plants;
- for grapes;
- for conifers;
- for potatoes;
- for cucumbers;
- for tomatoes;
- for strawberries;
- for wheat.
Types of fungicides
There are many classifications of antifungal products. Depending on the active substance, they are divided into chemical and biological. In the first case, the active element is a chemical compound. In the second group of agrochemicals, this role is played by a bacterium. The main advantage of biological additives is their low toxicity. Therefore, they are especially popular among summer residents and amateur gardeners.
According to the chemical properties of the mixture are divided into organic and inorganic. The first – have the following advantages:
According to the chemical properties of the mixture are divided into organic and inorganic. The first – have the following advantages:
- no heavy metals;
- good water solubility;
- compatibility with fertilizers.
Of the minuses of organic compounds, it is worth noting the low resistance. They do not last long in the soil. Microelements are the basis of inorganic preparations:
- potassium;
- manganese;
- nickel;
- grey and more
These funds are accumulated and stored in the ground for a long time. But they are not compatible with all additives used in the agricultural complex.
Distribution mechanism
On this basis, connections are divided into contact and system. The first – interact with pathogens on leaves and stems without penetrating into the culture. The fungus dies in the early phases of life. With contact agents, it is necessary to carefully process the foliage and shoots, leaving no free areas. Systemic fungicides protect from the inside. Most of these drugs are intended for treatment. Their advantages:
- performance – active substances penetrate the microflora in a short period of time;
- high performance – drugs allow you to fight infections that other pesticides are powerless;
- moisture resistant – you can treat the area before the rain, the suspension will not be washed away;
- a number of additional properties – some items combine the characteristics of insecticides.
Action and handling
According to the nature of the action, fungicides are divided into three types:
- protective – are used for prevention purposes, externally healthy crops are treated with such means, they are used during periods of high pathogenic risks;
- healing – agrochemicals in this category are also called curative, they are used when symptoms of the disease appear;
- immunizing – designed to build plant resistance to pathogens.
There are several methods for applying the substrate:
- pre-sowing seed treatment;
- soil disinfection;
- handling crops in vegetative stage;
- spray on dormant perennials;
- protecting warehouses for storing crops.
Thus, it seems possible to buy a fungicide for any purpose. When choosing a preparation for presowing treatment, it should be borne in mind that its effect will be maintained until the emergence of young shoots. When applied to the soil, the agent destroys not only pathogenic pathogens. It also kills pest larvae. For spraying, it is better to alternate systemic and contact agrochemicals.
Before using the substance, you should read the instructions. When applying, it is necessary to strictly observe the dosage.
