Question

Find out the amount of LAUDIS 4% SC for 6000 m\(^2\) maize plot if the rate of tembotrione application is 120 g/ha.

• A. 70 g
• B. 140 g
• C. 210 g
• D. 280 g

Hint:

Formulation amount = (Rate \(\times\) Area) Concentration.
Always convert area to ha.
LAUDIS 4% SC means 4% active ingredient.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
We need to calculate the amount of LAUDIS formulation required.
LAUDIS has 4% tembotrione.
The recommended rate is 120 g a.i./ha.

Step 2: Key Formula or Approach:
Amount of formulation = (Active ingredient required) (Concentration of formulation).
Active ingredient required = Rate \(\times\) Area.

Step 3: Detailed Explanation:
Area = 6000 m\(^2\) = 0.6 ha.
Active ingredient required = 120 g/ha \(\times\) 0.6 ha = 72 g.
Concentration of LAUDIS = 4% = 0.344.
Amount of formulation = 72 0.344 = 209.3 g.
This is approximately 210 g.

Step 4: Final Answer:
The amount of LAUDIS required is 210 g.
Hence, the correct option is (C).
