Pests spread massively in cereal and sunflower crops - advice on protection

13/05/2024 09:46

Lower temperatures and rainy weather at the end of April somewhat restrained the spread of pests in field crops and perennial crops. But with the increase in the marks on the thermometer bars, the conditions for their reproduction and spread became much more favorable.

Therefore, Ukravit experts recommend farms to conduct regular monitoring of fields and plantations and, if necessary, apply appropriate insecticides.

"The main weapon of an agronomist in the spring period is regular monitoring of fields and perennial plantations and insecticide spraying based on the results. And therefore, with the onset of stable elevated temperatures, the situation with pests must be kept under control. All the more so, as already today grain crops suffer from the harmful cockroach bug, striped fleas, cereal aphids and flies, bread leeches, and leafhoppers; the root system of crops is damaged by the larvae of a complex of soil pests," Oleksandr Myglovets, head of the company's agricultural technology department, said.

According to him, aphids and damage by weevils are noted in young sunflower crops in various regions. In fruit plantations, garden weevils, leafhoppers and sucking pests cause massive damage; The exit and resettlement of the hairy elk is ongoing.

"The situation with other crops is not too different either - they are all damaged by pests to a greater or lesser extent. And it is predicted that when the temperature regime stabilizes, the situation will worsen," the specialist noted.

To control common pests of winter and spring cereals, sunflower and other field crops, as well as fruit plantations, Oleksandr Myglovets recommends choosing the contact systemic insecticide Venon (clothianidin, 200 g/l + alpha-cypermethrin, 100 g/l). The combination of active substances of the drug provides a quick "knockout" effect and a long period of protective action against a complex of sucking and leaf-gnawing pests (including those resistant to pyrethroids) and prevents the emergence of resistance in them.

Clothianidin blocks postsynaptic cholinergic receptors, causing excessive overexcitation of nerve cells, and alpha-cypermethrin disrupts the permeability of cell membranes and acts as an inhibitor of sodium channels, as a result of which there is an excess release of acetylcholine during the passage of nerve impulses through the synaptic chain, and the pest dies due to strong nerve overexcitation.

 

On cereals, Venon effectively controls harmful beetles, aphids, thrips, bread beetles, and cereal flies. On the sunflower - types of scoops, weevils, bugs, aphids. In fruit, the insecticide does an excellent job with apple sawfly, thrips, aphids, fruit eaters, leafhoppers and others. The drug will also be useful in the fight against pests of rape, vegetables, corn and other crops.
