Insecticide Lannat is a highly effective drug against sucking and gnawing pests
Description of the drug
Lannat is a contact insecticide belonging to the carbamate group.The drug itself has a wide spectrum of action and, in direct contact with insects, destroys adults, nymphs, larvae, and also has a detrimental effect on laid eggs. Thanks to its translaminar action, it quickly penetrates into the leaf blade, where it creates a destructive concentration for sucking pests and affects them even on the underside of the leaf.
Compound
The main active component of the Lannat insecticide is methomyl, which, when it comes into contact with a pest, penetrates into its body. Thus, with direct contact, within a quarter of an hour after spraying the plant, the active substance affects up to 40% of the insects on it.
Varieties and forms of release
Lannate is available as a wettable white crystalline powder or 20% soluble concentrate with a slightly sulfurous odor.
In powder form, you can purchase the drug in a foil bag weighing 200 g and 1 kg. In liquid form, the insecticide is produced in canisters of 1 and 5 liters.
How does it affect pests?
The active substance methomyl contained in the insecticide is capable of blocking the hydrolytic enzyme acetylcholinesterase at the synapse in insects at the cellular level, thereby paralyzing them.
Signs indicating that the drug has reached pests first appear in hyperactivity and tremors of the limbs, after which paralysis of the body occurs and the immediate death of the insect.
The substance begins to act within 15 minutes after treatment, showing the destruction of up to 40% of pests. After 1 hour, up to 70% of insects can be affected, and in 4-6 hours, about 90% die.
The drug itself is used to combat more than 140 types of pests. Lannat shows high effectiveness against apple and oriental codling moths, grape moths, bunch moths and biennial leafrollers, winter moths, and white butterflies. The insecticide also does an excellent job of killing aphids, whiteflies, leafhoppers and thrips.
The drug is effective regardless of weather conditions. Retains its effect both at temperatures reduced to + 5 °C and up to + 40 °C.
The most favorable time for treatment is considered to be the period of laying the first eggs. Next, spraying is carried out when the larvae appear.

Fruit and berry crops
For fruit and berry crops, spraying is carried out at the rate of 600-1200 l/ha. The treatment is carried out in clear weather at a temperature of at least + 5 °C. It is necessary to spray the working fluid evenly over the entire leaf surface, including tree trunks when processing apple trees.
Garden flowers and ornamental shrubs
Treatment of garden flowers and ornamental shrubs with Lannat is carried out in the period before buds break, as this allows you to protect plants from larvae of harmful insects that have not yet hatched.
Spraying is best done in the morning in calm weather. First, the top of the bushes is treated, then the crown and branches, and lastly the trunk. In this case, you should avoid getting the drug on the ground.
Rules and frequency of processing
