CAPSANEM

 

Unit of packaging

Steinernema carpocapsae (entomopathogenic nematode)

Standard CAPSANEM pack size: blister in a box

Contains: 50 million larvae (third stage) in inert carrying material

Large CAPSANEM pack size: 2 bags in a box

Contains: 2 x 250 million larvae (third stage) in inert carrying material

 

Preparation of solution

• put the contents of the package into a bucket containing 5 litres of water (15-20°C)
• stir well and poor the entire content into the spray tank
• fill up with the required amount of water
• spray immediately after preparation
• use the whole package at once, since the distribution of nematodes in the pack is not homogenous!

 

Target

• larvae of soil and leaf-dwelling pests from the families of Noctuidae (noctuids)
• larvae of Pyralidae (a.o. Duponchelia fovealis)
• larvae of Tipulidae (crane-flies)
• larvae of the great pine weevil (Hylobius abietis)
• also effective against various pests belonging to the orders Coleoptera (beetles) and Orthopthera (f.e. mole crickets)

preventive	500000/m²	100	35	-	-
curative light	500000/m²	100	7-14	2x	rate applies to standard pack size and soil application
curative heavy	500000/m²	100	5-7	2x	rate applies to standrd pack size and soil application

 

Application and dose

• with a watering-can, irrigation system, knapsack or motorized sprayer
• to avoid blockage, all filters should be removed
• use a maximum pressure of 5 bar on sprayboom or pistol
• the spray nozzle opening should be at least 0.5 mm (500 micron)
• continuous mixing should take place to prevent nematodes sinking to the bottom of the spray tank

 

soil application:

• rates 0.5 million nematodes/m2, independant of amount of spray solution
• amount of spray solution strongly depends on target of application, use mimimum 3000 L/ha for application to control Duponchelia.
• water the crop before and after application
• spread the spraying solution evenly over the area to be treated
• keep the soil moist for the first 2 weeks after application

 

leaf application:

• use 0.25 million nematodes/m2 diluted in 0.1 L spray solution/m2 (= 1000 L/ha)
• a wetting agent improves efficacy
• make sure plants are uniformly covered with the CAPSANEM spray solution, but avoid runoff

 

Environmental conditions

• the humidity content of the soil must be high
• soil temperature between 12-32°C
• nematodes are very susceptible to ultraviolet light (UV): do not use them in direct sunlight
• leaf applications should be sprayed in the evening for minimum influence from UV light and maximum moisture availability for the nematodes

 

Storage and handling

• storage after receipt: see package for expiry date
• storage temperature: 2-6 °C
• in the dark

 

Appearance

Larvae (third stage): size 0.5-0.6 mm

Other stages: develop inside host

 

Mode of action

After application the nematodes search their surrounding area for passing insect larvae. The nematode enters the larval stage of the pest through a natural body opening. Once inside the larva the nematode excretes specific bacteria from its digestive tract before it starts to feed. The bacteria multiply very rapidly and convert the host tissue into products that the nematodes take up and use for food. The larva dies within a few days. The nematodes multiply and develop within the dead insect. As soon as the nematodes are in the infectious third stage, they leave the old host and start searching for new larvae. When there are no new hosts present, the nematode population will slowly decrease.

 

Visual effect

Insect larvae change colour and sometimes become slimy

 

Important!

The introduction rates of this product should be adjusted to the mode of action of the product and the results that can be expected in the crop where the product is applied. Your local Koppert consultant or recognized distributor will be able to advise you further.
