Pest facts and application notes:

• Carrot Root Fly - Carrot Fly is a serious and widespread pest of carrots, parsnips, celery, celeriac and parsley.  It is a weak flier and lurks around field and garden edges locating the target vegetable by scent. Attacks are particularly bad in old established gardens where the population builds up each year. It lays its eggs in the soil   adjacent to the plant, the eggs hatch out and the 9mm yellow/white maggots burrow into the roots. The maggots stay in the ground over winter, pupate and the life cycle starts again in the spring. Two further generations can appear during the year. The first and worst attack occurs early in the planting season; subsequent attacks are in autumn and winter in mild seasons.
  • • How to apply: Apply as a drench around roots of the plants or where pest is present either with a watering can with a coarse rose or a hose end feeder.
    • Area covered: Up to 60 sq.m
    • When to apply: April to July
    • Frequency: Repeat fortnightly throughout the growing season when pests are present
    • Notes: Apply along the rows and around the plants. The pests are next to the stems and roots of plants. 

• Cabbage Root Fly - The Cabbage Root Fly is a pest of all brassicas; cabbages, cauliflowers, broccoli, calabrese, Brussels sprouts, kale and root vegetables such as turnip, swede and radishes. It also attacks ornamentals such as stocks, alyssum and wallflowers. The fly has three generations from mid spring to early autumn and lays its eggs in the soil near to the stems of the plants. The eggs hatch out into white legless maggots up to 9mm in length which feed on the plant roots. In about 3 weeks the maggots are fully grown and become a small brown pupae, in another week the fly emerges ready to lay more eggs. This rapid lifecycle means that the cabbage root fly is a problem throughout the season until it overwinters as a pupae.
  • • How to apply: Apply as a drench around roots of the plants or where pest is present either with a watering can with a coarse rose or a hose end feeder.
    • Area covered: Up to 60 sq.m
    • When to apply: April to July

    • Notes: Apply along the rows and around the plants. The pests are next to the stems and roots of plants. 

• Cutworms - Cutworms are soil-dwelling caterpillars of several species of moth. In June and July the moths lay eggs in batches of 30-50 on leaves and stems. The emerging caterpillars are up to 40mm long and are often creamy-brown, greenish-brown or greyish-white in colour. They feed on many vegetables, fruit and ornamental plants and, after a couple of months, pupate in the soil. A second generation hatches out in August or September to feed, and to overwinter when the weather gets colder.

• Onion Fly - The onion is the most susceptible plant to the Onion Fly. Leeks, shallots and garlic can also be attacked as well as ornamental alliums. The maggots of the onion fly are up to 8mm long and white and are laid near the base of the plant or in the leaves. There are up to three generation a year, from the spring till late summer, the last generation overwintering as pupae in the soil.

• Leatherjackets - Leatherjackets are the larval stage of the crane fly or daddy-long-legs. Leatherjacket larvae are about 2.5cm (1" long), greyish black in colour, legless and with no distinct head. When you start to see the adult daddy-long-legs in your garden (towards the end of August) you will know that in a few days they will be laying eggs. These will hatch quickly, within two weeks. The young start to feed, continuing throughout winter, ready to gorge on roots in the spring.

    • Area covered: Up to 60 sq.m
    • When to apply: April to July
    • Frequency: Repeat applications are required to control the pest.
    • Notes:  Apply to the whole soil area. 

• Ants - Ants have 4 stages, egg, larvae, pupae (or cocoon in some species) and adult. Ants comprise three main castes, which have different roles, workers, queens and males. The life span of the ant varies with species from a few weeks to several years. The queen of the black ant (Lasius niger) can live for up to 15 years. There are about 50 species of ants living in the United Kingdom, but not all are native. The ones that are a problem to gardeners are Lasius niger, the common black garden ant, Lasius flavius, the yellow meadow ant and Myrmica species, red ants.

    • Notes: Ants do not tolerate the nematodes near their nests and move the nests away from these areas. Apply to the soil area or to individual ant nests.

• Sciarid - Sciarid Fly or Fungus Gnats are greyish-brown flies, about 3-4mm long and have slender bodies. They are found on the soil surface and leaves of pot plants. The maggots, which are white with a black head and up to 5mm long live in the soil and can damage vegetable seedlings or the base of soft cuttings.

    • Area covered: Up to 60 sq.m
    • When to apply: April to July
    • Frequency: Repeat applications are required to control the pest.
    • Notes:  Greenhouse pest - apply to the soil in pots, growing bags or open soil.

• Caterpillars - The caterpillar stage of the butterfly and moth's lifecycle comes in a vast range of sizes, shapes and colours. Fortunately very few of these are of any problem to the gardener that need controlling. The most common of the troublesome ones are the distinctive Large and Small Cabbage White Caterpillars, up to 40mm and 25mm long respectively. The Large Cabbage White has distinctive yellow and black markings and a hairy body. The Small Cabbage White Caterpillar is pale green with a velvety appearance. They both have two generations a year with caterpillars occurring from spring to early autumn.

    • Area covered: Up to 60 sq.m
    • When to apply: Apply when pest is present. Consider weekly applications until all pests have hatched out.
    • Frequency: 3 applications are recommended to control all pests hatching out.
    • Notes: Contact with pest is essential.

• Gooseberry Sawfly - The Gooseberry Sawfly is a pest that attacks gooseberries and red and white currants and can strip them of all leaves. All three species of Gooseberry Sawfly Caterpillars are up to 20mm long, pale green and with two of the species being heavily marked with black spots. Damage starts mid to late spring, but there can be several generations in a season.
  • • How to apply: Use a pump sprayer. Wet areas before applying and then spray the pests on the plants. Pests not directly sprayed will not be controlled. Avoid applying in direct sunlight.

• Thrips - Thrips feed by sucking sap and cause a discoloration on the upper leaf surface. Some species can spread plant virus diseases. Adult thrips are 1-2mm long and are yellow and brown, black or black and white. They lay their eggs on leaves, buds and petals and the eggs hatch out into larvae which pupate. Generation time can be only two weeks, so it is important to break the live cycle to control this pest.

• Codling Moth - The Codling Moth Caterpillar is small and white with a brown head. It burrows into the fruit of apples and pears in mid to late summer. By the time the fruit is ripe they have finished feeding and drop on to the bark of the tree and the soil immediately underneath to overwinter ready for the moths to emerge in the late spring. 
  • • How to apply: Use a pump sprayer. Wet areas before applying, then apply to the trunk, main branches and soil beneath the canopy.
    • Area covered: Up to 16 trees
