The hickory flower bud midge is the main pest harming hickory flower buds. Because the insect is tiny and concealed, its occurrence period is short, and the damage consequences are severe, once the effective control period is missed it will seriously affect hickory yield.
To effectively safeguard this year's hickory yield, scientific and technical personnel put forward the following on how to carry out effective control: First, promptly carry out crown spraying at the two effective control times, when the current hickory male flowers have grown to 2 cm and when the female flower buds have just formed, and ground spraying can also be adopted at present to kill the uneclosed pests underground; Second, select the right pesticide varieties, do not blindly increase the dosage or mix multiple pesticides, for ground spraying use 25% root insect net at 1:500, for tree spraying use 25% Guangzhi emulsifiable concentrate at 1:600-800 or Dusi Ben emulsifiable concentrate at 1:800, and note that when spraying for control the liquid must penetrate into the flower buds.
