Common “bugs” are whiteflies, aphids, psyllids, scale insects and so on. In recent years, “little insects” have become the main pests in agricultural production due to their small size, rapid development, and strong fecundity. The characteristics have become the focus and difficulty of agricultural control.

The occurrence of “small insects” is serious, and the prevention and control is becoming more and more difficult. How to choose pesticides in agricultural production and operation to achieve multiplier effect?

Then, of course, it is necessary to choose the appropriate pesticide according to the characteristics of the pests.

First, due to the characteristics of puncture and suction hazards, it is necessary to choose a drug with good systemic activity.

Second, because it mainly harms the new tissue (tenderness), it is necessary to choose a drug with good systemic activity and protection of the new tissue.

Third, it is often harmful to the back of the crop leaves and hidden parts (concealment). Therefore, there is a need to select agents with strong permeability and bidirectional conduction.

Fourth, due to the serious overlapping of generations and different insect states in the same period, it is necessary to select pesticides that can control multiple insect states.

There are many pesticides for the prevention and control of small insects. Among them, the conventional products are mainly nicotine and their compounds, which have many registration certificates and a large market share. They are currently the mainstream conventional small insect products; high-end products are spirotetramat and flonicamid. , Dipropionate single agent and compound products. With its unique ovicidal activity and bidirectional systemic conductivity, spirotetramat is more thorough in preventive medication, can control hidden pests, has a wide insecticidal spectrum, and has a long lasting effect. main force.
