Treatment of cultivated agricultural plants with insecticides prevents their damage by insect pests. Preparations with a large coverage of the species being treated and the insects that they are capable of destroying are especially valued. Let's consider the purpose and action of Vantex, the release form and composition, the rate of application and consumption. How to properly prepare the solution, is it possible to combine the drug with pesticides, how should it be stored and substitute products.
Composition and release form
The manufacturer of Vantex, Keminova A/S, produces the drug in the form of a microencapsulated emulsion in 1 and 5 liter canisters. The active substance is gamma-cyhalothrin in the amount of 60 g per 1 liter. "Vantex" has an intestinal and contact effect.
How the product works
Gamma-cyhalothrin blocks the conduction of nerve impulses. "Vantex" has a toxic effect when it comes into contact with an insect, when the pest comes into contact with the sprayed surface, or when the pest eats the leaves and stems of treated plants.
"Vantex" protects plants for 2-3 weeks, reduces the need for additional spraying or reduces their number. The speed of action of the insecticide is high; the first dead insects can be observed within half an hour after treatment.
The insecticide works effectively at temperatures from +8 °C to +35 °C, is not washed off from the surface of plants by rain, and is resistant to ultraviolet radiation and high temperatures. Has no phytotoxic effect when used in doses recommended by the manufacturer. With the constant use of Vantex, pests may become accustomed to it, so you need to alternate this insecticide with drugs whose substances belong to other chemicals. groups.
Purpose of the drug
"Vantex" belongs to the latest generation of insecticides, which explains its effectiveness, so it can be used on many crops against a number of common pests. Among drugs containing pyrethroids, the drug has increased activity and is stable due to the active substance, which is located in a 1-isomer molecule, as well as due to the release form - a microencapsulated suspension.
Consumption rate and use of insecticide
Norm for diluting Vantex:
- wheat, barley – 0.06-0.07;
- rapeseed – 0.04-0.06;
- pastures – 0.06-0.08 (early instar larvae), 0.12-0.16 (late instar larvae);
- apple tree – 0.2-0.35;
- sugar beet – 0.05-0.07 (from aphids, weevils, flea beetles), 0.07-0.15 (from moths);
- carrots – 0.05-0.08 (psyllids), 0.1-0.125 (onion fly);
- onion – 0.08-0.1 (thrips), 0.15-0.2 (fly);
- oil flax and fiber flax – 0.04-0.06;
- sunflower – 0.1-0.15;
- corn – 0.1-0.2.
All crops, except pasture plants, are sprayed against locusts when pests appear during the growing season. The solution consumption is different: for field crops and pastures - 200-400 liters per hectare, for apple trees - 1000-1500 liters per hectare, when sprayed from an airplane - 25-100 liters per hectare.
Pastures are sprayed when younger and older instar larvae appear. Treatment is single or double, the waiting period varies for different crops - from 7 to 56 days.
Spraying with Vantex solution should begin as soon as signs of pests appear. In case of mass infestation or if most insects are adults or are in the stage of older larvae, it is recommended to prepare the most concentrated solution. The volume of liquid used should be such that it can thoroughly moisten the leaves and stems of plants from all sides. The solution adheres firmly to plants and is not washed away by rain.
Safety precautions
In terms of toxicity class, the insecticide belongs to agricultural preparations with class 3, that is, low-toxic.It is allowed to work in protective clothing that covers the body; be sure to wear gloves, a respirator, and goggles. Spray in the morning or evening, in the absence of wind. If the solution accidentally gets on areas of the skin, wash off the liquid with water. The same should be done if the liquid gets into your eyes.
When preparing tank mixtures, Vantex should be added last. You can work on treated areas of fields and gardens 3 days after spraying, on pastures - after 30 days. You cannot pick berries and mushrooms in areas with wild vegetation that has been treated with an insecticide.
For bees, the toxicity of the drug is 1, which means that you cannot spray the drug on sunny days when insects are actively flying. The use of Vantex in fields and gardens near water bodies is prohibited; its active substance can be dangerous to fish.
Compatibility with other tools
We combine Vantex with pesticides that are used on the same crops and at the same time.
How to store it correctly?
The insecticide is stored for 3 years in a dry, ventilated warehouse at a temperature from -5 °C to +25 °C. After the shelf life has expired, the product is unusable and must be replaced with a new one. Store the solution for no longer than 1 day, after which it loses its effectiveness.
What can replace the drug?
With gamma-cyhalothrin, the chemical industry produces the drug “Danadim Power” in the form of a concentrated emulsion.
"Vantex" is highly effective against many pests of field and garden crops, wild vegetation and pasture grasses. The drug is effective even at low consumption rates. It acts not only on larvae, but also on adult pests.
