Boca Hydro Chelated Zinc EDTA 14% Water Soluble Micronutrient

Zinc Deficiency in Crops

Zinc deficiency can lead to a range of serious plant health issues. In citrus, peach, and grape, it typically presents as small, pale leaves with interveinal chlorosis. In pecans, it causes "rosetting," while in corn, it results in "white bud." Zinc deficiency can also cause fruit and nuts to develop bitter flavors and, in severe cases, lead to branch dieback in citrus trees.

Applying pure zinc products not formulated for agriculture can be harmful to plants. These industrial-grade zinc compounds—often used in tanning, ceramics, or manufacturing—are typically too concentrated, poorly absorbed, and can cause severe leaf burn. Only a small fraction of the zinc in these products is plant-available.

Role of Zinc in Plant Health

Zinc is vital for chlorophyll production, carbohydrate synthesis, and the conversion of starches into sugars. It also supports nutrient uptake and plays a key role in the formation of auxins—plant hormones that regulate growth and stem elongation.
