Herbicide Adjuvant Guide

XSEED Spray Oil

X-SEED Spray Oil  XSEED Label

Product Overview

XSEED is based on a unique blend of emulsifiers and environmentally renewable, super de-gummed Canola oil.

Because of high molecular weight of vegetable oils, and the relatively coarse spray deposit formed by XSEED it also helps to minimise spray drift, and run-off, while at the same time increasing the contact coverage and uptake of the chemical by the spray target.

XSEED will improve the effectiveness of herbicides and insecticides as well as providing:

• Reduced wind drift
• Improved wetting
• Improved rain fastness
• Improved sticking and bonding of spray onto plant surface
• Protection and spreading of agricultural sprays into and onto the target

As a result of these features XSEED significantly improves the performance of most herbicides, insecticides, fungicides and foliar nutrients resulting in a more cost effective and successful spray program.


Potential applications of XSEED include use with:

• Herbicides
• Insecticides: including new bio-insecticides suitable for Integrated Pest Management (IPM) Programs
• Protectant fungicides
• Foliar fertilisers and chelate trace elements
• Growth regulators and hormones
• Defoliates
• ULV Sprays as a bulking agent
• For micro encapsulation
• As a desiccation aid used to harvest crops such as potatoes XSEED can also be used to encapsulate pesticides by premixing the pesticides with XSEED to increase spray efficacy, rain fastness and facilitate tank mixing of incompatible products and preventing hydrolysis.


Rates are dependant upon quality of chemical required though a minimum guide is a ratio of 25% XSEED to active chemical volume premixed and added to the spray vat. For wettable powders or granular formulations add water at 1:1 ratio, mix into slurry, and add XSEED.

Always follow pesticide label instructions.

Tree/ Vine Weed Control

The drift reduction properties of XSEED make it an ideal tank mix partner for both contact and translocated herbicides used in orchards and vines.

If using translocated herbicides such as glyphosate or glufosinate it is essential to prevent contact onto green or growing tissue of trees (including young bark) as damage to the tree can occur.

XSEED will reduce potential for off-target damage by increasing droplet size and reducing drift.

Grape Vine Rust Mite Notes

XSEED is particularly useful as an adjuvant for wettable sulphur used to control grapevine rust mite (Calepitrimerus vitis Nalepa) as recommended at woolly bud stage prior to budburst (when using an IPM approach). Further application details to assist in the management of grapevine rust mite include:

• Wettable sulphur pre bud burst label rates are 500g/100L - 660g/100L.
• Temperature should be @15°C at time of application.
• Avoid frosty conditions.
• Use high spray volume around vine crown @ 900L/Ha, (or 600L/Ha for very young vines).
• XSEED added to the spray solution at 2% (10- 12 L/Ha minimum) may improve rust mite kill by 15-20%.

Spray Timing For Rust Mite

Possibly the most important aspect is that the critical spray window is at the start of rust mite migration, before feeding and egg lay. This is at woolly bud stage for most varieties except Cabernet Sauvignon, which should be sprayed between bud swell and woolly bud stage.

Growers should be aware that canola oil is phytotoxic to grape foliage if applied after budburst.


XSEED is compatible with most commonly used agricultural and horticultural products.

• Always check the label of the product to be mixed with XSEED.
• Do not use if the labels states that the chemical is not to be mixed with seed, vegetable or blended emulsifiable crop oil.
• Most seed oils can cause phytotoxicity in adverse climatic conditions.
• If a chemical label states that the product is to be used with a mineral oil or ‘Water miscible summer oil” please follow this recommendation and contact your reseller for an appropriate SACOA product (such as BIOPEST).
