Organica Bio Silica Barrier – Silica Sharps & Insect Irritant

Description

Organica Bio Silica Barrier is a highly effective spray on silica protectant designed to enhance plant defenses while maintaining essential air and nutrient exchange. This advanced formula reinforces plant surfaces with a tough, microscopic silica layer that acts as a physical barrier, providing protection against both environmental stress and microbial threats.

Ideal for fruit and foliage, this bio formulation helps strengthen plant tissue without clogging or coating stomata, ensuring your plants continue to breathe and absorb nutrients effectively.

Key Benefits
  • Micronised Silica Barrier: Adds a thin, protective cuticle layer that hardens leaf and fruit surfaces against stress and pests.
  • Dual Action Protection: Shields plants from insect irritation, environmental exposure (sun, wind, heat), and microbial attacks.
  • Preserves Plant Function: Supports airflow and nutrient uptake—critical for healthy plant metabolism and growth.
  • Organic Certified Input: Registered with Australian Organic (#442), suitable for certified organic farming.
  • Non-toxic & Eco Safe: Safe for humans, animals, and the broader environment when used as directed.
Application Instructions
  • Foliar Spray: Mix 100–150 ml per 10L of water or 1 - 1.5L per 100L of water. Apply using a fine mist sprayer until run-off is visible on leaves and fruit.
  • When to Apply: For best results, apply in cooler parts of the day - early morning or late afternoon. Avoid use during peak sun hours or when humidity is high.

Psyllids in Olive Trees

About Psyllids: Psyllids, also known as jumping plant lice or lerp insects, are sap-sucking insects related to whiteflies, aphids and scale insects. In Australia, there are hundreds of species of psyllid, most of which are of not of any economic significance. Most psyllid species are host specific and live and feed only on a group of closely related plants or a single tree species), including the psyllids which feed on eucalypts.

4 Factors In Grove Management To Focus On For Next Olive Harvest

The Grove Management Plan: Essential Areas to Focus On

A successful Grove Management Plan must cover these key areas:

Irrigation

"A grove without an effective irrigation system is unlikely to deliver consistent yields year after year. Many growers still underestimate the water needs of olive trees, and few actually monitor soil moisture levels. This is why so many groves have never achieved a commercial crop."  Marcelo Berlanda Specialist Olive Consultant

Water stress negatively affects flowering, fruit set, oil accumulation (oil production), fruit size (table olives), fruit quality, and overall tree health. However, many growers lack a proper system to monitor soil moisture or manage irrigation effectively. 

Marcelo recommends:

"Growers should inspect soil moisture weekly during spring and summer, and every two weeks in autumn and winter. Use a shovel to dig at least 400mm under the tree canopy to check moisture. If the soil is hard to dig, it’s too dry – even if the canopy shows no visible signs of stress." 

Advanced soil moisture monitoring tools can also provide reliable data on a digital display or computer dashboard. 

For optimal grove health, growers must consistently check soil moisture and prevent water stress.

Nutrition

As discussed previously, taking leaf samples is essential to assess your trees’ nutritional status. This information guides the creation of a fertiliser program, a critical component for boosting or maintaining yields.

Typically, no fertiliser is needed in winter, unless you’re addressing soil amendments. However, some groves have severe nutrient deficiencies requiring fertiliser even in winter. Where proper irrigation systems aren’t in place, growers must broadcast fertiliser before rain to allow rainfall to incorporate nutrients into the soil profile, an inefficient use of resources but often the only option.

When applying fertiliser in these conditions, target the area beneath the canopy and, if possible, cultivate the soil to improve incorporation and reduce product loss.

Olives need four essential nutrients: Nitrogen, Phosphorus, Potassium, and Calcium. Check product labels carefully. As a general guideline, aim for:

Pruning

Avoid pruning during the coldest part of winter and when it’s wet or foggy to reduce the risk of bacterial and fungal disease spread.

The main goals of pruning are to remove dead wood, reduce canopy size, restore tree balance, encourage healthy new growth, and increase fruit set in spring.

Tip: After pruning, apply a copper-based spray to protect wounds from infection by fungi and bacteria.

Pest and Disease Control

Pest & disease management is crucial for sustaining yield and tree health. Winter’s colder temperatures reduce insect activity, offering a prime time to tackle pest issues.

Set up a comprehensive Pest and Disease Monitoring Program. During winter, check-marked trees (previously affected by pests or diseases) every two weeks; in spring, check weekly. Look under leaves and on new growth for signs like crawlers, yellow spots, black sooty mould, or anything unusual.

Proactive, weekly management is essential for a successful grove.

Harvest Wrap-up: Australian Olive Growers Face Lower Yields After Unseasonal Weather

Unpredictable weather has challenged Australia’s 2023 olive harvest. Extended cold and wet periods across key growing regions shortened ripening cycles and reduced yields, according to the Australian Olive Oil Association. Despite smaller volumes, oil quality remains exceptional, with producers adapting to global shortages and shifting export opportunities.

Xylella Fastidiosa In Olive Trees: Symptoms, Spread, Management And Global Impact

Xylella fastidiosa is one of the most destructive bacterial pathogens affecting olive trees globally. Responsible for Olive Quick Decline Syndrome, it disrupts the tree’s vascular system, leading to canopy dieback, reduced fruit set, and eventual tree mortality. This in-depth guide examines symptoms, insect transmission, containment strategies, resistant cultivars, and the far-reaching economic impact on Mediterranean and global olive production.
