Walnuts
Walnut includes about 20 species of deciduous trees constituting the genus Juglans of the family Juglandaceae, native to North and South America, southern Europe, Asia and the West Indies. The trees have long leaves with five to 23 short-stalked leaflets. The male and female reproductive organs are borne in different, petal-less flower clusters on the same tree. The twigs contain a many-chambered pith. The fruit is a woody nut enclosed in a thick husk. California accounts for almost all the US walnut production.
Bloom
Flower production and bloom is an integral part to the development of a healthy crop. For a robust harvest to occur, significant flowering is necessary for fertilization. A number of key micronutrients are integral for flowering, and when they are not available or are deficient in the soil, this can lead to a diminished or reduced bloom. ZMC Express® provides a well-rounded mix of micronutrients to address numerous plant functions occurring during bloom. By delivering more than just one micronutrient, balanced interactions between nutrients within the plant are maintained.
Nut Fill
Nut Fill is an important and nutritionally taxing period within a plant. Phosphorus and potassium are critical nutrients required at this time, as they are responsible for translocation of proteins and sugars, water balance in the plant, production and utilization of ATP, root development and many other processes. The proprietary humectant system provided by Sugar Express® enables increased absorption and translocation of nutrients during this stage.
Walnut Husk Fly
Walnut Husk Fly is a mid to late season pest. Once a host plant has been infested damage to walnuts can cause staining of nuts as well as overall decline in yield. Nu-Lure® helps to increase control of insecticides used by attracting the adults to feed on application sites.
