Bi-58 Top

Why Bi-58 Top remains a staple in crop protection

In large-scale farming, when faced with a complex of pests that require immediate and systemic action, agronomists rely on field-tested tools. "Bi-58 Top," based on dimethoate, is an industry classic that excels where contact insecticides struggle, particularly against pests with hidden lifestyles.

The systemic nature of the product allows it to penetrate plant tissues, rendering the host plant toxic to sucking and chewing pests. This is critical for managing aphids, cereal flies, and mites that frequently inhabit the undersides of leaves or the inner parts of stalks.

Practical application scenarios

• Field crops (cereals, sunflower, rapeseed): Applied via spray during the vegetative stage to combat Sunn pest, cereal leaf beetles, and weevils. It effectively halts population surges and protects new growth.
• Orchards (apples, plums): Used as a powerful "stop" mechanism against codling moths and leaf rollers. It is frequently integrated into protection schedules to manage second and third generations of pests.
• Pulses and fodder: In cases of pea weevil or aphid infestations on fodder beet, the systemic action ensures coverage even in areas difficult to reach with standard spraying equipment.

Technical guidance for farm management:

The product is formulated as an emulsifiable concentrate, ensuring ease of mixing for spray tanks. Application rates range from 0.5 to 2 L/ha, depending on the crop and pest density. As a class 2 hazardous substance, strict adherence to safety protocols and re-entry intervals (20–40 days before harvest) is mandatory. To prevent the development of pest resistance, it is advised to limit application to 1–2 treatments per season.
