Carbosulfan

Tech Grade: 98%TC

Applicaton:

1. Rice:Apply during the early to mid-tillering stage for controlling stem borers, leafhoppers, and planthoppers. Use no more than 1-2 applications per growing season. The preharvest interval (PHI) is 30 days . For rice thrips, apply at 2000-3000x dilution . For brown planthoppers and leafhoppers, apply at 2-3 instar nymph stage at 150-200 ml/亩 (30-40 ml per application) .

2. Citrus:Apply for controlling aphids, leafminers, rust mites, and scale insects. For rust mites, apply when new shoots reach 1 cm at 1500-2000x dilution, repeat every 5 days for 2-3 applications (provides over 40 days control) . For leafminers, apply at early shoot stage or egg hatching peak at 1000-1500x dilution . Use no more than 2 applications per growing season. The preharvest interval is 15 days.

3. Apple: Apply for controlling aphids, leafminers, and leaf rollers. Use no more than 3 applications per growing season. The preharvest interval is 30 days . Apply at 3000x dilution for aphids and leafminers .

4. Cabbage (Brassica): Apply for controlling aphids and other pests. Use no more than 2 applications per growing season. The preharvest interval is 7 days .

5. Hairy Gourd / Wax Gourd (Benincasa hispida):
Apply for controlling thrips. Use no more than 2 applications per growing season. The preharvest interval is 7 days .

6. Cotton: Apply for controlling aphids (both seedling and summer aphids), bollworms, leafhoppers, and thrips. For seedling aphids, use at 3000-4000x dilution; for summer aphids (which are more resistant), use at 1500-2000x dilution . Use no more than 2 applications per growing season. The preharvest interval is 30 days .

7. Corn (Maize): Apply for controlling aphids and armyworms during the vegetative stage. Use 400-600 ml/ha (200g/L EC formulation). Add adjuvant for better coverage . Can also be used as a seed treatment for controlling seedling maggot and corn borer .

8. Vegetables (General): Apply for controlling whiteflies, caterpillars, aphids, thrips, and leafminers at the early pest stage. Use 300-400 ml/ha (200g/L EC formulation). Check crop sensitivity before application . For vegetable aphids, use 1000-2000x dilution; for American leafmin.

Cautions:

Maximum applications: Maximum 2 applications per growing season for most crops (cotton, citrus, rice) ; do not exceed 2 applications per season for rice and vegetables ; maximum 2 applications for cotton and citrus .

Application interval: Research suggests that spraying every 14 days is as effective as shorter intervals, allowing farmers to reduce insecticide use by up to 75% while maintaining effective control of cotton aphids .

Pre-harvest interval (PHI):

Cotton: 30-70 days (varies by formulation and region)

Citrus: 15 days

Rice: 14days

Brinjal (Eggplant): 5 days

Chilli: 8 days

Cumin: 17 days

Tobacco: 21-30 days (for Carbosulfan formulations)

Wheat: 30 days

Toxicity to aquatic organisms: This insecticide is highly toxic to fish and aquatic organisms (classified as Acute Aquatic Toxicity Category 1, H400) with long-lasting effects (H410) . The 72-hour LC50 for fish is 0.071 mg/L . It cannot be directly sprayed on water or near water sources . Due to its high toxicity to aquatic organisms, there are potential risks in the application of rice fields; avoid contamination of ponds, rivers, and ditches . Do not clean application equipment or dispose of packaging in or near water bodies .

Toxicity to other non-target organisms:

Bees: Highly toxic – avoid application during crop flowering periods, near apiaries, or on flowering weeds

Silkworms: Highly toxic – avoid use near sericulture areas and mulberry orchards

Birds: High toxicity – take protective measures for birds during application

Mammals: Moderately toxic (acute oral LD50: 51-101 mg/kg in rats) ; classified as Acute Toxicity Category 3 (H301: Toxic if swallowed) and Category 2 for inhalation (H330: Fatal if inhaled) ; also a skin sensitiser (H317)
