Aphid is serious problem on wheat. It occurs from wheat greening stage to wheat heading stage, which has severe impact on wheat yield.



Aphid causes direct and indirect damage to wheat.

Direct damage:

Aphid adults and aphid nymphs suck sap of stems, wheat leaves and tender ears of wheat. After the wheat seedling is damaged, leaves turn yellow and wheat plants stop growing. Eventually, it brings serious decline in tillers.

After wheat plants in the ear stage are damaged, wheat leaves turn yellow and wheat grains are not full, causing severe yield loss.



Indirect damage:

1.      Aphid secretes abundant honeydew on wheat leaves and tender ears, which are easily attached by dust, affecting wheat photosynthesis and causing wheat yield reduction.

2.      Aphid spreads wheat yellow dwarf disease, resulting in yellow wheat leaves, weak plants, and yield loss.

Wheat aphid occurs closely related to temperature and humidity. After wheat greening stage, wheat aphid breeds quickly if temperature rises and air is humid. According to data, wheat aphid breeds for 10 to 20 generations in one year and wheat aphid female can breed hundreds of aphid larvae in one lifetime.


Moreover, Wheat aphid occurs closely related to the water and fertilizer conditions in wheat field. Damage caused by wheat aphids are more serious in wheat fields with good fertilizer and water conditions, Especially, wheat aphid breaks out severely in wheat fields with partial application of nitrogen fertilizer and excessive seeding density.



How to control wheat aphid?

2.      It is recommended to applied thiamethoxam and isoprocarb mixed insecticide ‘Sniper’ for 2~3times to control cardinal number of wheat aphid in greening and jointing stage. Wheat also need to be applied ‘Sniper’ in full heading and flowering stage.
