For decades now, farmers and summer residents have been struggling with an insect that is destroying entire fields of nightshade crops at tremendous speed. Sonnet for the Colorado potato beetle does not act like many insecticides, to which the striped pest quickly gets used to and continues to reproduce. The emerging larvae are no longer afraid of poisons; they intensively eat the tops, leaves of potatoes and eggplants.
Description of the product
The drug Sonet is produced by the Technoexport company in the form of an emulsion packaged in ampoules or plastic bottles.The active component of the insecticide is hexaflumuron, which destroys the outer cover of adult insects, kills larvae, and destroys eggs. If you follow safety rules when preparing the product and processing plants, the drug is harmless to humans.
The active component of the insecticide promotes the dissolution of the wings and abdomen of the beetle, prevents the formation of chitinous cover, and destroys the insatiable offspring. Having eaten leaves sprayed with Sonnet, the insect stops growing and reproducing. The eggs laid by the female do not hatch into larvae.
The secret to efficiency
The main component of the insecticide retains its properties at high temperatures; after rain, the emulsion is not washed off with water. One treatment is enough to destroy a huge number of adult Colorado potato beetles and larvae. The drug lasts for one and a half months. The poison is absorbed into the leaves in just three hours. Insects do not develop tolerance to such an insecticide.
The secret of Sonnet’s effectiveness is that it has a negative effect on pests at all stages of their development, and is resistant to changes in humidity and sudden temperature changes.
What insects does it work against?
One spraying saves a potato bed from destruction by arthropod leaf beetles. Treatment must be carried out until the plant begins to bloom. The remedy for the Colorado potato beetle works well against other pests:
- lily hoverfly;
- codling moth;
- potato ladybug.
She quickly adapted to the redwing chemicals. The insect, which mates in early spring, eats the leaves and buds of the lily. When processed by Sonnet, it dies. To destroy the moth, the insecticide is combined with neurotoxic drugs.
It is not recommended to spray strawberries with the solution against the invasion of weevils; the emulsion worsens the taste of the berries.
Instructions for use
Before using the drug, you need to carefully read the instructions, which contain a detailed description of how this product works and how the solution is prepared. Shortly before processing the plants:
- The contents of the ampoule or 2 ml from the bottle are stirred in water.
- Add another 10 liters of liquid.
- Spray potato leaves.
This amount of insecticide is enough for one hundred square meters of beds. Less is needed for processing young bushes. It is easier to control pests when they first appear. Unlike other drugs, Sonet copes with insects in one spraying. The beetles die completely after 4 or 5 days, but treatment must be done in the morning and in dry weather.
Precautionary measures
The active component of the insecticide penetrates into the leaves, which insects feast on. Despite the claim that the product is not dangerous to humans, you should not ignore the rules for its use. To prevent the negative effects of Sonnet on the body:
- You cannot increase the dosage prescribed in the instructions.
- To reduce the release of toxic substances, you need to stop spraying plants in the heat.
- Treatment with insecticides must be done with gloves and a respirator.
- The emulsion must be diluted in a special container, and not in food containers.
When spraying potatoes before flowering, the drug does not get into the tubers, acts more effectively, and does not pose a danger to bees. Colorado beetles have not yet developed the ability to become accustomed to an insecticide that destroys the chitinous membrane.
Analogs
Many chemicals are produced to control insects.Fights against codling moths and mites, sawflies and cabbage cutworms, and kills Colorado potato beetles with the Karate insecticide. The main component of the product is lambda cyhalothrin. The emulsion is mixed with water, used sparingly, but protects plants from pests for no more than 2 weeks, so repeated treatment is required.
The drug Inta-vir, which is produced on the basis of cypermethrin, causes convulsions, affecting the nervous system:
- potato cow;
- codling moths;
- bedbugs;
- carrot fly;
- Colorado potato beetle.
Some pests develop resistance to this insecticide. Another disadvantage of the product is that it destroys insects that pollinate vegetables and fruit trees.
Aktara affects the digestive tract of Colorado potato beetles. After treating the leaves with the drug, these arthropods stop eating them and die a day later. The product is not only sprayed on potatoes, but also applied to the roots of flowering plants, currant and raspberry bushes to destroy scale insects and aphids.
In 2 days it copes with adults and larvae of the Colorado potato beetle Tanrek. Pests do not get used to imidacloprid, which is the active component of the insecticide; the product does not have a negative effect on potatoes and other vegetables.
The drug is not washed off with water and does not respond to decreases or increases in temperature. Protects against insects for three weeks. There is no need for re-processing.
Some gardeners do not want to use chemicals to combat the Colorado potato beetle, preferring biological agents. The striped pest does not like the smell of tansy and calendula. He doesn't like dill, garlic, or onions. If pests cannot be controlled in a gentle way, you have to select an insecticide.Sonnet is safe for humans, animals and beneficial insects, works for a long time, protects potatoes at an early stage.
