Tree Fruit

Citrus

One of the world most important fruit groups, citrus covers orange, lemon, grapefruit, tangerine, mandarin, lime, pomelo and all other subspecies. The genus Citrus of flowering trees and bushes was originally native to South Asia, East Asia, Southeast Asia, Melanesia, and Australia but is now grown widely across the world for fresh, culinary and many different types of juice and drinks.

When it comes to nutrition focus is on skin, flesh and juice quality and as the furit of citrus trees develops over many months and in some of the most challenging of climates, stress factors can impact both fruit number and quality at harvest so it is important to support the tree along with the developing fruits. Engage work with citrus grower across the world and developed a programme of product designed to optimise fruit quality, fruit number to minimise the impact of stress factors.

Fortify Cu

Fortify Cu (7-16-0+1.5% Cu) is a unique formulation of nitrogen phosphorus, copper and halide ions which complement each other to support plant growth, support tree health and reduce yield loss. With programmed application, Foritfy Cu will aid vascular flow, support root growth, maximise copper transport within the tree. Fortify Cu will support and maintain established yield and limit susceptibility to citrus fruit disease infections such as canker, black spot and citrus greening.

Aqualatus

Citrus crops are grown in some of the most challenging of climates as they require high uv level and temperatures to produce quality fruit.

Aqualatus is the world’s leading soil water saving technology with outstanding qualities to benefit soil water management, aggregation and growth. Its formula, unique to Engage, makes it an essential technology for the areas of the world where water availability is an issue.

Aqualatus’ unique formula is proven (300+ trials, over 12 years of data) to reduce water loss to crops by eradicating surface run off, dramatically reducing surface evaporation and slowing the natural gravitational movement of water.  The saving of water loss means that water application to crops can be reduced by 40-60% without any loss of crop development, yield and quality.

Bio-Chel Fe

Bio-Chel Fe Liquid (5%Fe) is an advanced micronutrient solution, organically chelated, to provide an highly effective iron for both root and foliar application. Using Bio-Chel chelation, the ratio of soluble lignin to iron in Bio-Chel Fe Liquid has been optimised to ensure full stability and availability over a pH range of 2-9. Unlike other chelated irons, Bio-Chel Fe Liquid contains natural surface active polymers. This ensures even iron distribution over the leaf surface without the need for additional adjuvants.

Another advantage to this is that the soluble Iron component remains hygroscopic. This helps keep the iron water soluble so that it can diffuse and penetrate into the citrus leaves even after the spray application has dried.

Bio-Chel Ca

One of the worlds most concentrated calcium chelate liquids, Bio-Chel Ca 10% CaO) is organically formulated from a sustainable, renewable resource and is 100% available calcium. Being pure calcium and organically chelated means calcium acceptance by fruit trees and developing fruit could not be higher, so efficacy is assured. The strong organic chelation within Bio-Chel Ca is important as it makes the product non-reactive and therefore ideal for application within all nutrient and foliar plant protection sprays.

Used regularly Bio-Chel Ca will optimise bud growth, flowering and fruit set and will deliver optimal levels of calcium to developing apples to ensure longer storage potential and no calcium related disorders.

Cypher

Cypher is a modified organic acid blend derived from plant active portions of lignin and leonhardite ore. It comprises of 100% organic acids which unlock nutrient potential for increased fruit tree growth and yield. Cypher is designed to condition soils which have become compacted, overloaded in bonded salts or have a higher than optimal pH. Regular use of Cypher will help maintain aggregate stability, optimal pH and active soil microflora and will de-bond ‘locked up’ nutrients such as calcium and phosphorus to ensure citrus can uptake important elements at higher levels.

Fortify Maxx

Fortify Maxx is a package of three chelated micronutrients and unique to Engage, plant extracts called ‘Phenophites’ taken from specific plant species naturally attuned to withstanding higher levels of abiotic and biotic stress.

Used via irrigation or foliarly applied the nutritional/phenophite package works in combination to increase the natural production of phenolic compounds from secondary pathways to significantly limit a plants susceptibility to stress of any kind. Unlike inorganic secondary pathway stimulants, Fortify Maxx does not create a residue as all the formulation is used by the growing crop.

Sentinel

Sentinel is a 10% advanced foliar Silicon is based upon the delivery of mono-silicic and salicylic acid to citrus crop tissues. Silicic acid is the only form of silicon citrus species will accept and its affects are highly beneficial to both the plant and developing fruit. Once applied, Sentinel is used by citrus to support superior growth and helps to build strong resilient cells which act as a physical barrier for the crop to reduce both susceptibility to damage from disease infection and predation from insect pests.

VerdeNT

VerdeNT is a unique nitrogen and calcium formulation combined with Arm U advanced, seaweed and MAS technologies specifically designed to fruit tree structure to enhance yield and quality. The nitrogen within VerdeNT is ‘locked’ in amine form and slow released which for foliar use means its use by citrus is very different. Unlike nitrate nitrogen foliar fertiliser, VerdeNT does not stimulate auxin production which promotes longer, weaker internodes and diverts calcium away from developing fruits. Growth habit with VerdeNT is more compact and stronger and removes the requirement for growth regulators and ensures continued calcium avilability to build stronger fruit.
