Natural Pest Control for Plants

Your first step to understanding Natural Pest Control For Plants

Plant Pests

In the previous posts we discussed different types of Soils, and Plant Nutrients and how to treat and restore balance in the garden. In the up-coming articles, we will be discussing some common Plant Pests & Diseases along with what Treatments,  Natural Pest Controls and Prevention Methods are available. A Pest is a living organism that can either be an animal, plant or fungus which by description is invasive, destructive or troublesome to it’s environment or the inhabitants. Natural Pest Controls for PlantsPests can also carry contagious germs and diseases which can have entered Australia from imported products. Once a plant pest or disease has inserted itself into the environment, they can be quite difficult and time consuming to eliminate. There are four main categories of pests including Insects, Mites, Nematodes and Gastropods. Natural Pest Controls for Plants

Insects

Insects are by far the most diverse group of pests, there are more than a million identified species. There are between six to ten million extant species and represent more then half of all known living organisms. The life cycle of insects can vary although most hatch from eggs and transition into adults. Insects are the only known pest to have evolved wings to adapt to it’s surroundings and co-evolved with Flora. It is said that before insects developed wings that they were not a very successful species. This then explains why the effect of them is much greater by gaining the ability of flight.

Mites

Mites are one of the smallest species of pest, most mites are tiny and less then 1mm in length. (can vary between 0.25 to 0.75mm) Mites have a simple, unsegmented body plan, although they seem to be almost invisible to the naked eye. The Mite’s impact on the surrounding environment can cause a large amount of damage. The majority of mites are blind and have minute bristles on their body. These act as sensors allowing them to easily navigate around. The life cycle of mites starts out as eggs, followed by Larva, Nymph and finally Adult stage. The eggs can take 2-6 weeks to hatch however the longevity varies between species but is still quite short.

Identification

Natural Pest Controls for Plants

Flower buds are one of the favourite places for Aphids to hide.

When it comes to identifying what type of pest is swarming in a garden, the first step would be to investigate. We will need to see if there are any critters on the plant, under the leaves or in the flower buds. Those are the most common places for them to hide. For insects, lets talk about Aphids, Scale, Mealy Bugs and Citrus Gall Wasps. The second step is to identify any type of pest activity.

Pest activity for Aphids are twisted and distorted leaves, flowers buds will often fail to open and sooty mould present. (caused by sap-sucking pests) Aphids love to colonise on young, fragile shoots including flower buds and under established leaves. The spread of Aphids can be quite detrimental if left untreated leading to a contagious infestation, fast. Natural Pest Controls for Plants

Pest activity for Scale are shell-like bumps on the plant and stunted growth of emerging shoots. Poor plant health and yellowing of leaves are also a sign. Scale are another sap-sucking pest and can be referred to as a parasite due to the large populations that begin feeding as soon as they find a suitable spot on the plant. They then can develop a hard-outer shell which looks like protective armour.

Pest activity for Mealy Bugs indicate a whiteish substance on the plant leaves, new growth is distorted and sooty mould could be present. Mealy Bugs are covered in white hairs and a mealy coating. They feed on plants while excreting a honeydew, known as a sticky substance that attracts ants.

Pest Activity for Citrus Gall Wasps include callous-like bumps on the stem of a citrus tree and loss of new or existing fruit. This fruit fiend can cause a lot of damage in the larvae stage. The adults lay their eggs in the stem waiting for them to hatch and the plant is then eaten from the inside out.

Treatment

When treating any type of insect infestation, we must conssider the surrounding environment, existing soil life and the present and future growth conditions of plants. Using an insecticide containing poison may kill off the insects, however the plant and beneficial Soil Microbes may become negatively impacted. This can result in an garden area that can’t support a healthy garden and the existing plants may slowly die off. Using Natural Pest Controls for Plants is a great way to eliminate the critters while keeping the plants best interest at heart. Some treatments may need to be re-applied however it’s worth it to avoid contaminating or destroying the garden.

Yates provide a wide range of Natural Pest Controls for Plants, some even treating more than one problem. The Yates Scale Gun is a great option when it comes to treating Aphids, Scale & Mealy Bugs by using natural ingredients. Controlling Citrus Gall Wasps is as simple as cutting off the infected stem containing the larvae and wrapping in a secure bag. Place the bag in direct sunlight, avoid doing this after winter as that is the time when the larvae are due to emerge. Using a sticky substance and string and tying it to branches will trap any returning adults leaving them stuck in their tracks. Although, if there is a small hole in the bump, the adults have already emerged leaving the larvae to do their dirty, damaging work.

We hope everyone finds this information on Insect Identification and Treatment helpful, as always please read the instruction labels on any insecticides and wear the correct personal protective equipment. We hope that everyone can win the war and are able to enjoy all areas of the garden pest free and safe for future growth.
