Compatibility table of fungicides with insecticides and rules for the use of drugs

A universal remedy for protecting the garden and vegetable garden from pests - tank mixtures. Often summer residents and farmers use ready-made purchased preparations. But you can cook them yourself. It is important to take into account the compatibility of fungicides and insecticides, of which the mixture will consist. A table of substance compatibility, as well as knowledge of the intricacies of technology and rules for use, will help to prepare the product in the country.

Can fungicides be mixed with insecticides?

During spring and autumn work, the summer resident has to treat the plants with several means - from insects, fungus and diseases. Spraying a plant first with one drug and then with another takes a lot of time.

Insecticides and fungicides can be mixed in a shared container and sprayed in one go. But before preparing a mixture from available funds, you need to check their compatibility..

When selecting components, consider:

• the action of insecticides - systemic, contact, protective, broad spectrum;
• developmental phase, insect species - gnawing, inactive, rapidly multiplying;
• the appointment of fungicides - prevention, treatment of the fungus.

Anti-rodent chemicals are also used in solutions.

Compatibility table of insecticides, fungicides and micronutrients

Those preparations are compatible, which coincide in terms of processing, physical and chemical properties. The solubility of substances in water affects the order in which they are added to the container during mixing.

Legend:

• F - fungicide;
• And - insecticide;
• + - compatible;
• - - not compatible.

Means of the same action are usually not mixed. Most often, the mixture includes a drug against insects and fungus. But with excessive activity of parasites, viruses in one tank dissolve several substances similar in purpose.

Useful Facts About Mixing Popular Chemicals:

• Bordeaux liquid is not added to the solution, but sprayed separately;
• Fitoverm and Aktara preparations are incompatible. Baikal-Em, Fitosporin are combined with each of them separately;
• antifungal biological product Pseudobacterin-2 is compatible with chemicals, but not compatible with succinic acid;
• against the codling moth, mixtures of antibacterial drugs and pesticides effectively work: bitoxbacillin, lipidocda with fufanon, kemifos.
• biological preparations with bacteria work well with chemical fungicides.

Do not mix fungicides with sulfur in the composition and oil preparations. Biological substances with a fungal base will be destroyed by antibiotics.

What are tank mixes

Tank mix is ​​a combination of several chemicals for the destruction of garden pests and diseases. Substances in solution are capable of enhancing each other's action. A single treatment with the mixture is more beneficial than repeated exposure. Plants and soil adapt better to the preparations, and the gardener saves time.

Insects and viruses get used to the constant action of one poison. They have no resistance to a complex solution, so it is more effective. The garden will have to be processed less often. For a farm of several hectares, less complex preparation is required compared to the usual one. This will save money, reduce the consumption of raw materials and water, and keep soil fertility longer.

Ready-made tank mixes contain two or more components. Weed control herbicides are also mixed with insecticides and fungicides. The benefits of the composition are added by liquid fertilizer, a growth stimulator. Chemical compounds inhibit plants, and fertilizing, stimulants strengthen their immunity.

What to dilute a mixture of pesticides

Pest control chemicals are mixed in water. Requirements for the quality of the base:

• room temperature, from 10 to 22-25 degrees;
• filtered, spring;
• transparent.

River, rainwater is not suitable for mixing. Sludge, bacteria in it can affect the chemical reaction.

Water with mineral salts is not suitable. If it is tough, the chemicals will precipitate.

A soap solution can be added to help the contact pesticides adhere to the plants. But it is useless for system tools. Soap is alkali. It will act as a neutralizer for acidic drugs.

What can and cannot be mixed?

Manufacturers indicate recommendations for mixing insect repellents in the instructions on the package. If there are no special instructions and restrictions, you can use the following tip on how to combine fungicides and insecticides:

• test compatibility by experience - mix a small amount of drugs in a bucket of water;
• combine substances recommended for a certain growing season.

Formulations intended for spraying plants during flowering will not work or will have little effect after harvest.

During the preparation of a homemade mixture, incompatible substances change the physicochemical properties of each other. The result is a toxic solution with sediment that will clog the spray holes and the mixture will coat the plants unevenly.

A solution of incompatible drugs is dangerous due to phytotoxicity. Substances accumulate in plants and cause burns, which can be noticed after 2-3 days. Also, the effect of the poison can manifest itself in a week in the form of fallen leaves.

To check the compatibility of the components and water, prepare a test solution. As a result of a chemical reaction, a precipitate may appear, and its consistency may change. In this case, you need to replace one of the components or use water from another source. The disadvantage of making a homemade tank mixture is that you have to achieve compatibility of substances by trial and error.

You cannot mix:

• fungicides and minerals: boron, iron, zinc, magnesium. Fertilizers based on them also cannot be added to the solution;
• preparations containing sulfur and calcium;
• acids and alkalis;
• sulfur and boron with oils;
• boron and lime;
• calcium with phosphorus, sulfur, magnesium, iron.

Lime increases toxicity, therefore Bordeaux liquid is not added to solutions due to lime in the composition. An excess of growth stimulants will have the opposite, suppressive effect.

Factory tank mixes contain auxiliary substances that balance the properties of various chemicals: solvents, stabilizers, antioxidants, preservatives, acidity and evaporation regulators.

Safety measures in the use of tank mixtures

In order not to harm the plants and prepare a homogeneous solution, it is important to follow the order in which the chemicals are mixed:

• water-soluble;
• dry granules;
• concentrates, suspensions;
• oils, emulsions.

Surfactants, aqueous solutions, liquid fertilizers and stimulants are added last.

If the mixture exfoliates, flakes, sediment appear, it cannot be used - the constituent preparations are incompatible and toxic.

The mixture must be prepared and used on the same day. Over time, it loses its beneficial properties. It is better to use substances with a state register number on the package.

Spraying rules

Recommendations for treating the garden and vegetable garden with insecticides:

• do not spray diseased, damaged stems;
• disinfect the garden in good, warm weather;
• do not simultaneously treat insects and weeds;
• top dressing with inorganic salts should be applied after spraying with pesticides.

Plants attacked by insects are vulnerable to chemistry. In the heat, the preparations can burn the leaves and stems in the sun. In the spring, you need to process plants on a sunny day without wind. Wait a week between treatment with tank mixture and herbicides.
