The scale insect is the enemy of the apricot tree. It sucks the sap, and lightens the trunk to cause the flowers to have no fruit. The heavy one causes the tree to die. Recently, many farmers have consulted by phone or consulted the science and technology service hall to consult the prevention and control methods of apricot trees. To this end, the following measures can be taken for the prevention and control of scale insects on apricot trees throughout the year:
The following four medications can be effectively controlled throughout the year to prevent and cure the scale insects: 1 before and after the “rainwaterâ€. At this time, the apricot tree buds sprouted during the germination period. The wind and clear weather were selected, and the trunk and branches were sprayed with a high-purity agent of pyrethroids to kill the wintering nucleus that crouched on the branches. 2 "Amazing" before and after. At this time, the apricot flower buds have been red, and the 3 to 5 wave of sulphur sulphur mixture is re-sprayed, which is conducive to insecticide and disease prevention. 3 Falling flowers show the leaf stage. Spraying the sweep can control residual scale insects and wintering aphids. 4 after the fruit is thinned. It is controlled by a mixture of insecticide, bactericidal and acaricidal spray. The above four medications are indispensable. It should be noted that dichlorvos and dimethoate should not be used on the apricot tree, otherwise it will cause fruit drop.
