Benefits
DOES NOT HARM EARTHWORMS
COMPARABLE EFFICACY TO SYNTHETICS
LOW DOSE
DOES NOT CAUSE PHYTOTOXICITY
ZERO RESIDUES
0 RE-ENTRY AND POST-HARVEST PERIOD
Nematicide for use in organic production
NEMAKILL is an OMRI listed nematicide for use in organic production to control soil nematodes on food and non-food crops. NEMAKILL is made of natural oils and acts directly when in contact with the insect. NEMAKILL is an effective product to enhance the action of pesticides and fertilizers when they are used in a mixture.
- OMRI listed
- Highly effective & uses low rates & has equivalent activity and residual control to that of synthetic insecticides
- Does not require PHI (Pe Harvest Interval) nor REI (Reentry Interval) periods
Mode and Mechanism of Action
Uses
Can be used to impact nematode populations affecting a broad variety of crops. Nematode populations it affects include sting nematodes, lesion nematodes, root-knot nematodes, rice nematodes, soybean cyst nematodes, lance nematodes, citrus nematodes, stubby root nematodes, needle nematodes, sheath nematodes, Northern root knot nematodes, Columbia root knot nematodes, Southern root knot nematodes, alfalfa stem nematodes, Pratylenchus spp., foliar nematodes, strawberry spider mites, Radopholus simillis, and others.
Use Rate
32 – 48oz/ac
Once it penetrates the soil, NemaKill® acts through contact, inhalation and translaminar action, penetrating the lipid and protein membranes of the nematode’s outer walls, causing collapse and death.
NemaKill® releases chemical alleles that produce nematicidal effects and affect the behavior of nematodes, impairing their mobility and causing paralysis and mortality. These compounds are non-toxic in the rhizosphere.
| Crop | Pest | Rate (L / 200 L water) | Observations |
|---|---|---|---|
| Traditional and export vegetables, berries, extensive crops, flowers and ornamentals. | Meloidogyne spp., Radopholus similis, Pratylenchus spp., Helicotylenchus spp., Tylenchulus spp., Ditylenchus spp. | 2 - 4 | In short-cycle crops, make 3-4 applications per crop cycle at intervals of 15 to 30 days. Start applications 10 days after transplanting or plant emergence. |
| Banana, avocado, citrus, pineapple and other perennials. | 3 - 7 | For perennial crops, apply at intervals of 90 to 120 days. |
Characteristics
- Offers efficacy comparable to synthetic products.
- Promotes the development of functional roots.
- Does not harm the environment.
- Does not affect beneficial fauna or pollinating bees.
- Due to its favorable toxicological profile, it does not require EPA
- Federal registration in the USA.
- Low dosage requirement.
- Can be used in any crop for any nematode species, both in the soil and on foliage.
- Controls soil pests such as symphylids, fungus gnats and wireworms.
- Provides control over slugs and snails.
- Does not affect the color, taste or odor of treated crops.
- Paralysis: Within the first 12 hours, it immediately causes knockout effects in some cases. This symptom is an irreversible sign of death.
- Death: Insects do not recover, leading to rapid mortality within 24 hours after application.
Monitoring
It is recommended to conduct evaluations 1 to 3 days after application.
Crop
Traditional and export vegetables, berries, extensive crops, flowers and ornamentals.
