Features of Thiodicarb
Thiodicarb can kill eggs, larvae, and some mature insects. Its ovicidal activity is extremely high, demonstrated in three ways: 1) The pesticide solution can contact unhatched eggs, preventing hatching or causing the larvae to die before reaching the second instar; 2) Eggs laid within three days after application cannot hatch or complete early developmental stages; 3) Newly hatched larvae are effectively poisoned when they chew through the egg membranes.
Due to the incorporation of thioether bonds in its structure, thiodicarb also exhibits high insecticidal activity against resistant pest strains that detoxify via oxidative metabolism. It works rapidly but has a short residual effect, typically lasting only 4 to 5 days.

Application
Thiodicarb is mainly used to control lepidopteran pests, such as cotton bollworm, pink bollworm, leaf rollers, heart-cutting worms, caterpillars, small cabbage looper, and tea tortrix, as well as some beetles and dipteran pests. However, it is generally ineffective against aphids, mites, leafhoppers, planthoppers, and thrips.
1. For cotton bollworms and pink bollworms during peak egg-laying periods, apply 50–80 grams of 75% wettable powder per acre, mixed with 40–60 liters of water for spraying. In years with prolonged pest occurrence, spray again every 10 days.
2. For vegetable pests such as cabbage loopers, tobacco budworms, small cabbage loopers, beet armyworms, and armyworms, apply 40–60 grams of 75% wettable powder per acre, mixed with 50 liters of water for spraying. Harvest can be done 7 days after application.
3. For fruit tree pests like heart-cutting worms and leaf rolling moths on apples, pears, and peaches during peak egg-laying periods, use a 1,000–1,200-fold dilution of 75% wettable powder for spraying. The time from application to harvest is: 21 days for apples, 14 days for pears, and 7 days for peaches.
Tobacco:
4. For tea tortrix and tea leaf roller moths during peak egg-laying periods, apply a 1,000–1,500-fold dilution of 75% wettable powder for spraying. Harvest can be done 14 days after application.
5. For tobacco budworms during peak egg-laying periods, apply 30–50 grams of 75% wettable powder per acre, mixed with 50 liters of water for spraying.
6. For rice pests like the first and second generation stem borers, apply 50–65 grams of 75% wettable powder per acre. For the rice leaf roller, use 30–50 grams, mixed with 50–60 kilograms of water for spraying.
7. For wheat pests like armyworms and wheat leaf midges, apply 20–40 grams of 75% wettable powder per acre, mixed with 40 kilograms of water for spraying.
