Non-toxic, bio-degradable, non-selective weed control products made from plant acid extracts and natural ferments.
ACTIVE INGREDIENTS: Natural plant acids
GREEN & ORGANIC WEED CONTROL PRODUCT RANGE
- SOFT BROAD LEAF (CU Product No. P102163)
- TOUGH & STRONG LEAF (CU Product No. P102164)
- SEED STOP GERMINATION OF WEED SEED (CU Product No.101940)
WEED CONTROL ACTION: The application of a foliar spray of the plant acids act by destroying the inner cell structure of the leaf which results in the disruption of physiological plant processes such as photosynthesis and the immediate collapse of the leaf. There is no known systemic action, so re growth from roots or bulb on aggressive weeds requires follow up treatment. Active ingredients are biodegradable and volatilized by sunlight.
WEEDS TESTED FOR CONTROL ACTION: Small flowered quick weed (parviflora galinsoga); Cape (thorny) pigweed (amaranthus retroflexus); Common purslane or pigweed (portuloca oleracea); Clover; Crabgrass; Yellow sorrel (Oxalis pes-caprae); Knot weeds (Polygonum salcifolium); Dandelions
GERMINATION INTERCEPTOR: The application of a light soil drench of SEED STOP onto the surface of recently tilled beds when preparing for planting of seedlings has a pre-emergent action as the acids quickly penetrate seed tissue thereby inhibiting germination of weed seeds.

REGISTRATION: Product mix under development. Use for trial purposes only.
WARNING: Avoid contact with eyes and skin. The corrosive, oxidizing action can cause irritation to eyes and drying and mild erosion on skin surface. Keep out of reach of children, uninformed persons and animals.
PRECAUTIONS: When applying, wear protective clothing and gloves to protect skin and goggles to protect eyes. Wear a gas mask to protect from inhalation of vapor. Do not eat, drink or smoke while handling this product. Prevent contamination of food or feeds, drinking water or eating utensils. Wash yourself after use or immediately after accidental skin contact. In the case of eye contact, rinse with plenty of running water. Do not re use container.
DIRECTIONS FOR USE:
RATE OF APPLICATION 10 to 50ml per m2 depending on weed density and type.
- Apply as directed only.
- Any standard spraying equipment can be used, but should be reserved for weed control application only. Do not use high pressure spraying equipment. Rinse equipment thoroughly after use.
- Do not dilute for application. Apply at full strength only.
- Agitate mixture while applying
- Apply in hot, sunny, windless conditions for best effect.
- Leaf surface should be dry when applied. Avoid application just prior to rain.
- Apply early morning when leaf stomata are open for penetration of active acids.
- Spray on targeted weeds only. Avoid spray drift onto crops.
- Apply as a full cover spray on leaves and stems to wet only. Do not to allow to runoff.
- Application rate will vary per Ha. This will be determined by the density, age and the extent of weed growth, type of weed, crop planted and area to be treated. Application should therefore be adjusted per application from 10 to 50ml per m2 as required.
- Damage to weeds will be visible almost immediately.
- Emerging and young weeds are controlled with 1 application
- Aggressive, tough weeds might require 2 or 3 applications during the season to eradicate, but growth is stunted after each application.
In the absence of natural mulch, newly disturbed ground immediately tries to cover and protect the soils living ecosystem with “so-called weeds”. Weeds will grow only where they find conditions suitable for their needs; therefore a farmer can create conditions for weeds to flourish.
Weeds are pioneer plants. Their function is to protect the soil surface from erosion and prepare the ground for future plant generations by breaking soil with tap or extensive root systems.
They can be soil imbalance indicators as certain weeds flourish in pH, nutrient deficient soils, such as pigweed indicates low phosphate, or where soil structure and aeration is not optimal. Chickweed is an indicator of rich soil with good humus and nitrogen content.
Organic farmers consider weeds as another element in their organic practice that should be adapted to benefit production by protecting the soil surface, to conserve moisture and prevent excessive weed growth. Cultivated weeds should be left in situ to mulch and be broken down to compost to benefit and feed the soil ecosystem. The roots of weeds which remain after cultivation will decompose to add humus to the soil which then feeds plant and soil life. Where these weeds roots were the soil structure is improved by the formation of channels for penetration of water and air to ventilate and aerate the soil. Weeds roots exude sugars which maintain the variety of beneficial microbes in the soil. Weeds create plant diversity to break mono cropping. They can act as a trap crop for insect pests and a host breeding area for a variety of beneficial insects.
WARNING: DO NOT use conventional herbicides.
Weed control is one of the biggest challenges of large scale organic farmers in South African conditions.
The organic standards regulations for weed control list the following approved methods of weed control:
- Choose appropriate crop species and varieties
- Appropriate crop rotation programme
- Mechanical cultivation procedures
- Thermal weeding using a flame torch
- Manual control – hand weeding
- Companion planting
- Under sowing and intercropping
