Profile
Introduced in 1956. Carbaryl inhibits acetylcholinesterase (AChE) by covalent (irreversible) reaction with the enzyme at the acetylcholine binding site, blocking hydrolysis of acetylcholine and resulting in hyperexciattion.
Key Features & Benefits
- Broad-Spectrum Control
- Low Odour
- Residual Protection: Provides good residual protection on foliage
- Fruit thinning: Thought to be superior as a thinning agent for apples, without fear of russeting as there is no surfactant in the formula.
Toxicity
Acute oral (LD50, mg/kg) rats (male) 264; rats (female) 500; rabbits 710
What is Carbaryl 800WG Insecticide and how does it work?
Carbaryl 800WG is a Group 1A carbamate insecticide containing 800 g/kg carbaryl, formulated as a wettable granule for control of certain insect pests in fruit, vegetable, field crops, pastures and ornamentals as listed in the Directions for Use. It acts mainly by contact and ingestion as an anti‑cholinesterase compound, inhibiting acetylcholinesterase in insects and causing nervous system failure and death.
On which crops and situations can I use Carbaryl 800WG?
Registered uses include tree and vine crops (avocados, citrus, grapes, longans, litchis, macadamias, mangoes, pome fruit, stone fruit, coconuts, feijoa/guava), fruit and vegetables (melons and other cucurbits, potatoes, raspberries, beetroot, turnips/swede, sweet potato) and field crops, pastures and ornamentals (cereals including maize and sorghum, duboisia, lucerne, pastures and pasture seed crops, elm trees and ornamentals).
What key pests does Carbaryl 800WG control?
It controls a wide range of chewing and sucking pests including leaf beetles, caterpillars, heliothis/budworms, armyworms, grasshoppers and locusts, leafrollers, codling moth, lightbrown apple moth, oriental fruit moth, pear/cherry slug, leafhoppers, weevils, bugs and various beetles, as specified against each crop in the Directions for Use tables.
Are there limits on how often I can apply Carbaryl 800WG?
Yes, the label states that you must not apply Carbaryl 800WG more than four times per season to avocados and not more than three times per season to mangoes, and you must not apply it by air or use it in home gardens.
How do I mix Carbaryl 800WG for spraying?
Fill the spray tank half full with water, add the required amount of Carbaryl 800WG and mix thoroughly, then add the remainder of the water and mix again; when tank mixing with spray oils, add the oil and water first, then the pre‑mixed Carbaryl 800WG, maintaining agitation while filling and spraying.
What is the difference between dilute and concentrate spraying on the Carbaryl 800WG label?
Dilute spraying uses high water volumes up to the point of run‑off, with a set rate of product per 100 L, whereas concentrate spraying uses lower water volumes and a proportionally higher product rate per 100 L so that the same total amount of product per hectare is applied as in the dilute spray; the label explains how to calculate concentrate rates from a known dilute volume.
When should I spray Carbaryl 800WG for best results?
In general, you should apply at the first sign of pest activity and repeat as necessary at the intervals specified in the critical comments, ensuring thorough coverage of foliage, fruit or trunks as directed for each crop and pest.
Can Carbaryl 800WG be mixed with other products?
Carbaryl 800WG may be mixed with one of copper oxychloride, dimethoate, sulphur, summer spray oil, thiram, zineb or ziram, but must not be mixed with lime sulphur, Bordeaux mixture or other alkaline materials; when adding summer oil, add the oil to the water first, then the Carbaryl 800WG.
What pests and rates does Carbaryl 800WG control in tree and vine crops?
- Carbaryl 800WG is registered on avocados, citrus, grapes (butt treatments), longans and litchis (non flowering/non fruiting), macadamias, mangoes, pome fruit, stone fruit (not cherries), coconuts and some other tropical fruit trees.
- Key pests include Monolepta beetle, citrus leaf eating weevil, lightbrown apple moth, yellow peach moth, fruit piercing/orange fruit borer, Fuller's rose weevil, bronze orange bug, spined citrus bug, pink and white wax scale, macadamia nut borer and twig girdler, fig leafhopper, codling moth, pearleaf blister mite and pear/cherry slug, with typical rates between 65 and 130 g/100 L plus summer oil where indicated.

|---|---|---|---|
| Cereals (including Maize and Sorghum) | Australian plague locust, Wingless grasshopper, Yellow winged locust, Migratory locust | 700g–900g / ha | Apply when pest appears and repeat as necessary. Use higher rate where high insect pressure occurs. Use sufficient water for adequate coverage. |

What pests and rates does Carbaryl 800WG control in ornamentals and elm trees?
- Carbaryl 800WG controls elm leaf beetle in elm trees and a range of chewing and sucking pests in ornamentals, including green vegetable bug, potato moth, European earwig, cabbage white butterfly, cabbage moth, native budworm, loopers, leaf‑eating ladybird and pumpkin beetle.
- Elm trunk band treatments use higher rates to protect trees from serious defoliation, while foliar sprays and general ornamental sprays are used at lower rates, with a strong recommendation to test a small area first because of variable plant sensitivity.
Ornamentals Application Guide
Rate: Rates are given per 100 L water for dilute spraying. For concentrate spraying in suitable ornamental situations, follow the General Instructions and industry best practice.
Critical Comments: Apply at the first sign of pest activity and repeat as necessary, following special instructions for trunk banding of elms and test‑spraying ornamentals due to potential phytotoxicity.
| Situation | Pest | Rate | Critical Comments |
|---|---|---|---|
| Elm Trees | Elm leaf beetle | 2.5kg / 100L | Apply to the trunk of the tree in December, when the larvae are first observed on leaves. A repeat spray should be applied 4-6 weeks later, if large numbers of larvae are found on the leaves. To the trunk of a tree, apply a half meter wide band at a height of 1.5 metres or above. On large trees, the upper surface of branches, where they meet the trunk, should also be sprayed. Apply the spray to the trunk, at (a rate of) no more than 1L per m². The larvae are exposed to the chemical when they crawl down the trunk to pupate. This treatment will not eradicate the pest, but will protect the tree from serious defoliation. |
| 125g / 100L | If large numbers of larvae threaten to defoliate small specimen trees, a carbaryl spray may be applied to the foliage. Repeat spray when required. This treatment will not eradicate the pest, but will protect the tree from serious defoliation. | ||
| Ornamentals | Green vegetable bug, Potato moth, European earwig, Cabbage white butterfly, Cabbage moth, Native budworm, Loopers, Leaf eating ladybird, Pumpkin beetle | 130g / 100L | Apply at first sign of pest activity
and repeat as necessary. NOTE: Because of the wide range of ornamentals and their pests, phytotoxicity and efficacy of this product cannot be guaranteed, so use a small test area before widespread use. |

How should I manage resistance when using Carbaryl 800WG?
Carbaryl 800WG is a Group 1A insecticide and repeated use can select resistant biotypes, so it should be used according to any local resistance management strategies and rotated with insecticides from other mode‑of‑action groups where possible; Kendon advises consulting local agronomists or the company for resistance advice.
What personal protective equipment and re‑entry rules apply?
When handling granules and spray, wear cotton overalls buttoned to the neck and wrist or equivalent clothing, a washable hat and elbow‑length chemical‑resistant gloves, avoid contact with skin and eyes, and wash thoroughly after use; re‑entry into treated areas is restricted until sprays have dried, or until day 6 for hand‑harvesting after airblast or ground‑boom application, unless specified protective clothing is worn.
What key environmental and bee‑safety precautions are on the Carbaryl 800WG label?
Carbaryl 800WG is very toxic to aquatic life and toxic to bees, so sprays must not drift onto streams, rivers or other waterways and must not be applied to plants in flower while bees are foraging.
How does Carbaryl 800WG differ from Carbaryl 500SC?
Carbaryl 800WG is a higher‑strength 800 g/kg wettable granule insecticide, while Carbaryl 500SC is a 500 g/L suspension concentrate insecticide; both cover many similar fruit, vegetable, field crop, pasture and ornamental situations, but their registered pests, rates and withholding periods are not identical. Always select the product whose label explicitly lists your crop, pest and situation, and follow that label’s Directions for Use as the final authority.
