� e Adjuvant Advantage

…in the mix tank …between the spray tip and the leafStrong Chelating Agents - Ensures the water solubility required for plant uptake and utilization.

Anti-Evaporants - Achieves greater effi ciency of the applied nutrients by preventing the evaporation of micro-droplets before the target is reached.

Buffering Agents - Improves stability of the spray solution and provides optimum nutrient availability when tank mixing with many common crop protection products.

…on the leafSurfactants - Evenly distributes the spray solution on leaf surface to maximize effi cacy and crop safety of foliar applied nutrients.

Humectants – Re-activates dried residual deposits, allowing for plant uptake over a prolonged time period.

Miscibility - Application and handling effi ciencies result from tank mixing WUXAL formulations with many common crop protection products.

Stickers - Greatly reduces nutrient wash- off loss due to irrigation and rainfall by holding the solution on the targeted leaf surface. Download the smartphone app from

Foliar Strategies for Rice

Wuxal Program for Rice¹Pass Timing Products Rate Purpose

1 At tilleringWuxal Triple 1 qt/acre: Balanced NPK for root and shoot development.

+ Wuxal Zinc 1 pt/acre: Very important for enzyme functions related to growth and development and for efficient utilization of phosphorus.

2At panicle initiation up to booting

Wuxal Combi Mn 1 qt/acre:Balances N and K for late season protein sufficiency and starch movement into the grain, with S and micros to provide stay green and catalyze plant health.

+ Wuxal K25 1 pt/acre: Bolsters leaf K and S, essential for N-use efficiency, carbohydrate movement into the grain and leaf disease suppression.

3 At floweringWuxal Combi Mn 1 qt/acre: Same as 2nd pass.

+ Wuxal K25 1 pt/acre: Same as 2nd pass.

¹Always follow label requirements for rates, timing of application, adjuvant requirements, and mixing order of all tank mix combinations.

Zinc (Zn) Deficiency Symptoms

Zinc (Zn) deficiency is the most widespread micronutrient disorder in rice (Oryza sativa), and, next to nitrogen (N) and phosphorus (P) deficiency, Zn deficiency is now considered the most widespread nutrient disorder in lowland rice.¹,² Zn is a critical nutrient for adequate growth hormone function in roots and shoots, enzyme function, and efficient utilization of phosphorus.

Zn deficiency causes multiple symptoms that usually appear two to three weeks after transplanting (WAT) rice seedlings; leaves develop brown blotches and streaks that may fuse to cover older leaves entirely, plants remain stunted and in severe cases may die. Those that recover will show substantial delay in maturity and reduction in yield. ¹,³,⁴

Zn deficiency has been associated with a wide range of soil conditions: high pH (>7.0), low available Zn content, prolonged submergence and low redox potential, high organic matter and bicarbonate content, high magnesium (Mg) to calcium (Ca) ratio, and high available P.¹ High soil pH and perennial wetness appears to be the main factor associated with the widespread Zn deficiency in rice production.¹,²,⁵
