Imidacloprid
CAS NO.: 105827-78-9
Imidacloprid is a systemic insecticide.It acts as an insect neurotoxin and belongs to a class of chemicals called the neonicotinoids which act on the central nervous system of insects with much lower toxicity to mammals.
Function
Imidacloprid is widely used for pest control in agriculture. It can be applied by soil injection, tree injection, application to the skin of the plant, broadcast foliar, ground application as a granular or liquid formulation, or as a pesticide-coated seed treatment.
Other uses include application to foundations to prevent termite damage, pest control for gardens and turf, treatment of domestic pets to control fleas, protection of trees from boring insects, and in preservative treatment of some types of lumber products.
Uses and Dosage| Crop | Pests | Rate of Use | Application |
| Rice | Plant hopper | 21-31.5 g/ha. For 35%SC 15-45 g/ha. For 20%SL | Spray |
| Cotton | Aphid | 15-30 g/ha. | |
| Rice | Rice plant hopper | 30-45 g/ha. | |
| Citrus | Leaf miner | 2500-3000 times |
Benefits
1. Based on laboratory rat studies, imidacloprid is rated as "moderately toxic" on an acute oral basis to mammals and low toxicity on a dermal basis by the World Health Organization and the United States Environmental Protection Agency.
2. It is rated as an "unlikely" carcinogen and as weakly mutagenic by the U.S.EPA.
3. This agricultural chemical is not listed for reproductive or developmental toxicity.
Note
1. Imidacloprid is one of the most toxic insecticides to bees. The acute oral LD50 ranges from 0.005µg a.i./bee to 0.07µg a.i./bee, which makes the product more toxic to bees than organophosphate dimethoate or pyrethroid cypermethrin!
2. The farm chemical is highly toxic to four bird species including Japanese quail, house sparrow, canary, and pigeon.
