Protecting beet crops: A practical look at «Expert Trio»

Managing weed pressure in sugar and fodder beet fields is a challenge every season. «Expert Trio» (Expert Trio k.e.), produced by Nanjing Essence Fine-Chemical Co., Ltd, is a reliable tool for post-emergence control. As an operator, what I value most is its selectivity; it clears the weeds while keeping the crop healthy.

Targeting the threats

The formulation relies on a blend of desmedipham, phenmedipham, and ethofumesate. This mix is highly effective against key competitive weeds that can ruin yields if left untreated. In my experience, it handles the following with ease:

• Common lambsquarters and redroot pigweed;
• Shepherd's purse and common chickweed;
• Black bindweed and common ragweed;
• Purple deadnettle and field pansy.

On-field performance

The emulsifiable concentrate (EC) formula is convenient. It mixes well in the tank and doesn't clog nozzles, provided the water quality is decent. Since this is a systemic, post-emergence foliar herbicide, timing is everything. You need to hit the weeds while they are still young and actively growing.

The application rate ranges from 1 to 3 liters per hectare, depending on the field's weed density. You can perform up to 3 applications, which is typically enough to keep the crop clean throughout its sensitive phase. With a hazard class 3 rating, it requires standard protective measures, which is perfectly manageable for any professional farm crew.

Why it works

The primary advantage of «Expert Trio» is its selective nature. Unlike harsher alternatives, it doesn't cause significant growth stress to the beet plants when used at the correct rates. By opting for this systemic approach, you reduce the need for manual weeding, which is a massive operational saving. If you manage the timing correctly, it provides consistent results that help reach the harvest with minimal weed competition.
