What kind of insects does triazophos mainly kill?

Triazophos can be used in rice, cotton, vegetables and other crops to control pests such as borer, rice planthopper, aphid, cotton red spider, cabbage worm, Leiden, leek maggot, ground tiger and so on. Among them, the rice insects are mainly Chilo suppressalis, Chilo suppressalis, Chilo suppressalis and Rice gall midge. Cotton worms are mainly cotton bollworm, aphids and blind bugs.

(1) during the peak incubation period of Chilo suppressalis and Chilo suppressalis, 20% EC 150 ml, 60% EC 34 ml 50 ml, 20% microemulsion 80ml 120 ml, 15% microemulsion 100ml 150ml or 20% water emulsion 100ml 150ml, add water 50ml spray, or add water 75ml spray coarse spray, the efficacy period is about 7 days.

To Chilo suppressalis medinalis, before the peak stage of the 2nd instar larvae, 125-150 ml per mu of 20% EC and 50-60 L of water were sprayed, and the efficacy period was about 7 days. For rice thrips, when the leaf tip begins to roll leaves, the mu is sprayed with 20% EC 50ml / mu, water 40ml / mu and water 40ml / mu, and the efficacy period is 57days. For planthoppers, in the young nymph stage, 20% EC 75ml / mu and 60ml / mu water were sprayed on the base of rice, and the efficacy period was about 7 days.

For rice gall midge, 40% EC 180-240 ml per mu and 50-60 L water were sprayed during the peak egg hatching period. For rice weevil, 40% EC 50ml / mu and water 50ml / mu were sprayed at the overwintering site around the rice field in early spring, about 1 week after Honda transplanting seedlings (to control overwintering adults) or 3 weeks after transplanting seedlings.

(2) Helicoverpa armigera to Helicoverpa armigera, from the peak spawning period (large occurrence year) to the spawning peak period (medium occurrence year), spray with 150ml of 20% EC and 50ml of water per mu. When the number of insects is large and the occurrence period is long, spray once every 5 days. For Helicoverpa armigera, during the peak spawning period, use 20% EC 100ml / mu and spray 50ml / mu with water.

In the generation with a long occurrence period, spray it again every 7 days. To control cotton aphid, use 20% EC 50ml / mu, control bug mu with 75ml EC / mu, spray 40ml / mu with water, and the efficacy period is 5 / 7 days.

(3) before the 3rd instar peak of Pieris rapae and the 1st and 2nd instar larvae of Plutella xylostella, the vegetable pests were sprayed with 100ml / mu EC and 40ml / mu water. Control leek maggots, 3% granule 3-5 kg per mu, sprinkle.

(4) Sweet potato weevil is sprayed with 40% EC 1500-2000 times liquid.

(5) the land tiger is mixed into the soil with 20% EC 300-600 ml per mu.

(6) when the egg rate is more than 1%, the apple tree peach heart borer sprays 40% EC 1000-2000 times.

Note: triazophos is toxic to silkworm and prevent pollution of sericulture when spraying. It is toxic to fish and should not be used in fish culture rice field.
