Additional Information

Application information

Application prior to full emergence of 1st trifoliate leaf may cause temporary yellowing of soybeans. This effect is transient and has no effect on yields. Adequate soil moisture is necessary for optimal efficacy. Sufficient rainfall to moisten the soil to depth of 5cm is generally sufficient. If no rainfall within 7-10 days, a shallow cultivation or rotary hoe is recommended.

Post-emergent applications of FirstRate require the addition of a non-ionic surfactant at 0.25% v/v plus liquid fertilizer (28-0-0 or 32-0-0) at 2.5% v/v.

Pre-harvest interval: 65 days
