Shatangju to be harvested

Here comes the second farmer: care about the countryside, care about agriculture, care about farmers, and talk about farm affairs!

After citrus picking, we choose appropriate chemicals to control the diseases and pests, which will bring many benefits to our management after spring. The environmental conditions of pests and diseases in winter are not conducive to survival, and the activities of pests and diseases are weak and relatively concentrated, which is convenient for prevention and control.

Under normal circumstances, orchards with serious diseases such as macular disease, sand skin disease, canker disease, rust tick, red spider, soot disease and moss will appear.

Macular disease and sand skin disease:

It is recommended to spray first and then cut, and then spray the pesticide once after pruning, and use it in turn. Difenoconazole propiconazole+chlorpyrifos+mancozeb+foliar fertilizer+ethiconazole can be used; The mixture of stone and sulfur is used alone, and it is sprayed evenly through the leaves and branches by washing.

It is suggested to cut before spraying, and combine with other pest control to focus on the control of canker. If the rate of diseased plants with canker disease is below 3%, the diseased branches, diseased leaves and large branches with many diseased spots should be cut off first, and taken out of the orchard for centralized burning. If the diseased plant rate is more than 3%, it is suggested that the whole garden be destroyed and replanted with other fruit trees; Available foliar fertilizer+zinc thiazole+chlorpyrifos+mancozeb or prochloraz; Use only the mixture of sulfur and stone or Bordeaux solution, spray it evenly through the leaves and branches by washing, and spray it again every 2~3 days.
