FAQ’s

The leaves on my oak tree are covered in a white silvery layer. What is this and how do I treat it?

This is caused by the fungus powdery mildew. The best would be to apply Funginex on the leaves of the plant as low as possible as the product is systemic and will only move up in the plant.

I have heard a lot about Root Rot and Root diseases. How do I know if my plants are affected and how do I prevent these diseases?

Root rot can be easily identified by the dark looking and slimy feeling root system. Because most of us see the plant above the root zone, you’ll notice an overall unhealthy look about your plant, first. The leaves will start wilting (soggy looking), and start developing dry, brown blotchy spots. Root rot” is a common waterborne disease that can seriously affect indoor and outdoor plants year round. “Pythium” is a generic term for several different root rot and stem rot fungus species (including Pythium, Verticillium, and Phytophthora, and Fusarium). Root rot is also known as “damping-off” in seedlings. Use Fungi-Nil as a drench before planting any plants.

My roses have developed brown and yellow spots on the leaves. How do I treat this?

This is caused by the fungus called rust – the treatment would be Funginex or Dithane Neotec WG or for a ready to use fungicide Fungi Gun.
Rust is regularly confused with Black Spot which also occurs commonly on roses.

I have recently had invasive trees felled. New growth appears to be sprouting from the stump, how do I get rid of this?

The use of Garlon 4 would help stopping in the green regrowth of the tree.

Herbicides often refer to ‘broadleaf weeds’ – what are these?

The dandelions, clover and sorrel is probably the best example of a broadleaf weed. The leaves are “broad” as opposed to the “narrow” leaf of a grass plant.

What is a ‘selective’ and ‘non-selective’ herbicide?

Selective herbicides are used in lawn care or around nursery or garden plants once weeds emerge. A selective herbicide is used to kill weeds, but does not kill the valuable plant.

Non-selective herbicides are the herbicide of choice for people who want to kill all vegetation in an area. These types of herbicides are generally used in building projects, near fences, driveways and within industrial complexes.

What is the difference between a contact and a systemic insecticide?

Contact insecticides generally control a pest as a result of direct contact.
In practice, contact insecticides must be applied with a good coverage of spray droplets in order to make contact with the target.

Systemically-acting insecticides are taken up by plants relatively quickly via the roots or above-ground parts, and are then transported and re-distributed within the vascular system. They can also move between cells by diffusion.

Trans-laminar Insecticides with only local systemic activity must arrive directly where the pest is located, or they must be distributed very evenly over the plant surfaces from which the pest is likely to take them up.

My conifers are turning brown and appear to be dying, what is problem and what can I do?

Each year from March – August the Cypress Aphid infects conifers and the damage is only visible in spring use Plant Protector, Aphicide Plus or Insecticide Granules Plus

Every year my clivia’s get infested with a horrible worm. What is this and how can I prevent the terrible damage they cause?

The black and yellow worm is called a lily borer. You can use Eco Insect Control SC or Garden Ripcord concentrates or No Insect Outdoor Ready To Use

Is it true that Organic Fertilisers are less likely to ‘burn’ than Conventional Fertilisers?

When anyone makes the claim, “This fertiliser won’t burn,” my immediate reply is, “And Then it won’t feed, either.”The identical property which makes food elements available as plant nutrients – high solubility – will also make them likely to “burn” or injure plant tissues. The burn may be immediate or it may be delayed, but if the soluble ingredient which causes this condition is present in excess amounts, burn is almost inevitable.

I recently purchased an organic insecticide. The leaflet refers to a ‘..shorter withholding period’. What does this mean?

The withholding period (WHP) is the period that must elapse between the last application of a pesticide and harvesting.Follow this link to visit our Natural Gardening page.

Are organic fertilisers and pesticides as effective as Conventional ones?

Yes they are they are just formulated from natural sources.

Are natural pesticides still poisonous?

Yes, they are. The product was designed to kill a specific pest. The only difference is that a natural pesticide is less persistent in the environment, it breaks down quicker.

What exactly is meant by a ‘short withholding period’?

The withholding period (WHP) is the period that must elapse between the last application of a pesticide and harvesting.

What makes a product ‘qualify’ to be sold as an Organic or Natural product and is there a difference between these 2 terms?

Organic in scientific terms means a molecule that consists mainly of a carbon skeleton with other elements such as hydrogen, oxygen, nitrogen, sulphur, phosphorus and a few others as contributing building blocks. The majority of modern pesticide molecules are organic and fit in 100% with the scientific classification of organic.

We have a severe rat infestation. How do I get rid of rats permanently?

The best solution would be to lookout for any open areas where the rats could be entering into, and seal the areas. Using a bait e.g. Storm or Supa-kill will help eradicate the rats.

What is the difference between a single dose and a multiple dose application?

Single-dose anticoagulants are more toxic because they bind more tightly to the enzyme that makes blood clotting agents. Multifeed anticoagulants, are not easily excreted from the body, and they can be stored in body fat.

Everyone talks about the damage rodenticides do to owls and other birds. Is there an ‘environmentally friendly’ rodenticide I can use?

Yes, there is new Ridak it is multifeed rodenticide with reduced secondary poisoning.
