Directions for Use – General Recommendations

Treatment should be applied when pests are present

For turf applications cut the grass prior to application

Avoid applications in direct sunlight, evening applications are best

Apply in wet humid conditions

Ideally apply during rainfall or irrigate prior and after application (except for

foliage sprays where nematodes should remain on wet canopy e.g. thrips)

For soil drenches, the soil should be moist and remain as such for at least 2

weeks after application

Slug lifecycle

Individual slugs are capable of breeding throughout the year but do so typically in times of favourable conditions, warm and wet weather

Adults are hermaphrodites and once mated are capable of laying up to 500 eggs in batches of 20-80. Peak egg laying in Mar/Apr and Sep/Oct.

Eggs are laid in unexposed locations to avoid hot and dry environments and take 2 to 3 weeks to mature and hatch

The emerging immature stages start feeding on susceptible plant material taking one to two months to reach sexual maturity

Vine weevil (Otiorhyncus sulcatus) lifecycle

All adults are females and reproduce parthenogenetically

Adults emerge in May/June and lay several hundreds of eggs each around host

plants (2 - 40 cm deep)

Eggs hatch after 1-3 weeks depending on temperature and the larvae feed on the

root system

Larvae overwinter in the soil as pre-pupae and pupate in spring (some adults may

overwinter)

Life cycle is completed typically in 11-12 months, however populations in glasshouses

may have two generations per year with adults emerging as early as March.

Warmer conditions mean that they can reproduce all year round and all stages may

be present at all times, so keep monitoring.

tearing up turf to find the grubs

Adults do not cause any damage on turf

Without secondary damage symptoms often confused

150 years

Carrot root fly lifecycle

Adult females lay eggs in May and early June on the soil surface around the plants

Eggs hatch in a few days and the maggots feed on and in the roots for about 4 weeks

Larvae pupate near the roots until July/ August when the adult flies emerge. The new flies lay more

eggs, which again mature to maggots. This second generation causes plant damage in August/

September

Larvae that develop in Autumn will spend the winter as pupae in the soil or as maggots in the roots

Larvae from the second generation cause the greatest damage. There can be a third generation in

late Autumn (November). Over-wintering carrots are particularly susceptible to this generation

Susceptible plant types

Attacks a wide range of cultivated plants, including:

Carrot

Parsnip

Parsley

Celery

Carrot root fly (Psila rosae)

Damage

Larvae tunnel inside tap roots of umbelliferous plants, leaving behind a rust-coloured material

Larval feeding causes scars and distortions of roots leading to a reduced yield and allows an entry point for secondary pathogens that cause decay

Affected plants, with large infestations, may become yellow, stunted, and die. However, more often the plant tops continue to look healthy. Maggots often continue to feed in stored carrots

Seedlings can be killed

Larvae are yellowish or white and up to 9 mm long

Pupae are red/ brown and barrel-shaped 7 to 8 mm long

Adult flies resemble house flies and are grey-brown in colour with a darker stripe

along the back of the abdomen, red eyes and about 6-7 mm long

Nemasys®


150 years

Cabbage root fly lifecycle

An adult female has a short lifespan (12 to 15 days at 20°C) and lays about 150 eggs. Laying begins

about 3 days after the adults have emerged from the ground in spring

Eggs are deposited in the ground in small clusters in the immediate vicinity of the plant stem and hatch

4-6 days later at 15-20°C. High temperature leads to high mortality of eggs and young larvae

Once the egg has hatched, the larva buries itself in the ground and penetrates the roots where it forms

galleries in the most tender parts. Once the larva is fully developed (about 3 weeks depending on

temperature), it leaves the plant and pupates

Nemasys®


Pupae development lasts about 20 days. When soil temperature

is above 22 C in the summer, pupae remain in a state of rest

(quiescence). Pupae enter diapause in the autumn and

reassume their development in spring when the soil warms up

Three to four generations per year, from the beginning of April to

October. Precise timings vary from region to region and year to

year

Cabbage

Cauliflower

Brussel sprouts

Turnip

Damage

Infested brassicas make poor growth and may wilt and die, especially recent transplants in early summer

Affected plants show tainted purplish leaves which turn yellow and often dry up

Occasionally the maggots will tunnel into individual buttons on Brussel sprout plants

Cutworms are soil dwelling caterpillars that cut down young stems as they feed at or below the soil surface. There are also species of climbing cutworms that feed above ground.

Eggs are white/yellow in colour and measure about 0.5 mm in diameter.

Larvae typically measure 2 to 3 mm in length when newly hatched. Species can be quite distinct from each other and their coloration can vary (pink, brown, gray, black, spotted, stripped). Fully developed caterpillars may reach 50 mm in length.

Pupae are red/brown in colour and measure about 20 mm in length.

Adults are about 20 mm long with a 40mm wingspan.

Cutworm lifecycle

After 4-12 days, eggs hatch and larvae develop through 6 or 7 larval instars,

which may take from 15 days at 26˚C to 3 months depending on temperature

and species.

Larvae pupate in the soil and adults emerge after around 11-13 days at 25˚C,

and typically live for around 4-10 days. They may go through as many as 3

generations per year depending on temperature.

Females begin laying eggs 2-5 days after

emerging.

Each female can lay hundreds of eggs singly or in

small batches, typically on low-growing plants or

soil.

Eggs are white/green and vertically ribbed, deposited either individually or in small groups

The pupa measures 20 mm and is contained within a white cocoon which darkens to brown/ black

Adult forewings are gold/ bronze, typically with two silver spots although possibly just one, and the hindwings are pale. The wingspan measures about 40 mm

The common gooseberry sawfly is the most troublesome pest of gooseberries. It can have three generations a year, with the larvae active between late April and September
