Tennessee, USA (1994): Treatments increased yield over the control
Cotton requires an adequate supply of boron—especially during the boll development stage—or boll shed may occur, which reduces yields.
Visual symptoms of boron deficiency may not occur until the deficiency has become moderate or severe. Use the results of soil tests and/or plant analyses to help assess the potential for boron deficiencies to ensure adequate boron supplies for your crop.
Boron deficiency is the most common micronutrient limitation in forest plantations. It occurs in many countries, particularly in exotic plantations of eucalypts and pines, but also in plantations and natural stands of native species on soils altered by macronutrient fertilization, liming, fire, or erosion.
Foliar nutrient sprays are commonly applied to fruit trees. Boron is immobile in most plant tissues so boron may not be readily transported to developing flower buds. Solubor can be effectively applied with dormant oil-insecticide sprays during the dormant stages of most fruit trees.
Boron is a micronutrient required for all plant nutrition. The main functions of boron relate to cell wall strength and development, cell division, fruit and seed development, sugar transport, and hormone development.
Multiple foliar sprays of Solubor applied alone or with insecticides will ensure boron supply during the critical stages of flowering and berry development in grapes. Preplant soil application of Granubor plus foliar sprays of Solubor during the season are recommended for soils testing low in available boron.
The efficacy of some pesticides may be affected by increased pH of the pesticide tank mixes. Inclusion of an appropriate buffer to control the pH of tank mixes is suggested for those pesticides whose efficacy is known to be reduced by increased pH.
Murcia, Spain (2005): Better performance of sodium borates versus non-sodium borates (MEA liquids).
Peanuts require boron, especially during the pod development stage, or “hollow heart” may occur, possibly reducing quality and yields. Read more about how Solubor and Granubor can help ensure adequate boron supply.
Research in California has shown that foliar applications of Solubor increased pistachio yields. The best time for foliar application is from the late dormant to the early bud stages. Soil applications of boron are not as effective as foliar applications in supplying sufficient boron for flowering.
