Why "Priboy" has become a go-to for weed control

When working with rapeseed and soybeans, annual broadleaf weeds remain a major challenge, often choking out young crops. Field experience with the soil herbicide "Priboy" from F.Superus Co., Ltd. shows that its selectivity allows for crop treatment without the risk of phytotoxicity, provided dosage guidelines are strictly followed.

Operational tips and application

As an operator, I can confirm that the emulsifiable concentrate mixes well in the spray tank. The primary strategy here is pre-emergence application. This requires proper soil preparation: the field surface should be fine-textured, free of large clods, so that the active ingredient (clomazone) can form an even "screen".

• Effectiveness: With a rate of 0.15–0.25 l/ha, "Priboy" creates a reliable barrier for germinating weeds.
• Systemic action: The substance penetrates through sprouts, inhibiting chlorophyll production, which gives crops a clean start.
• Safety: The product is classified as hazard class 3, requiring standard protective measures but causing no significant handling difficulties.

It is important to remember: this is a single-application tool. The maximum limit is one treatment per season. This requires the agronomist to be precise, timing the application immediately after sowing, before the crops emerge.

Practical advice

The main factor is moisture. As a soil herbicide, "Priboy" performs best when there is at least minimal moisture in the topsoil layer. If the soil is too dry, efficacy drops, so I recommend planning the application based on weather forecasts or incorporating it lightly if the equipment allows. With the right approach, the field remains clean during the most critical growth stages of rapeseed or soybeans.
