Seal all the fecal holes with wet mud. However, aluminum phosphide is very toxic and should be used with safety. (2) Giardiasis: parasites occur in apples and pears and occur one or two years later. They endanger the superficial cortex, phloem and cambium. Cortical areas of the affected area are dehiscent. Red mucus exudates outside the corpus callosum, commonly known as “Chang Hong oilâ€. . The helix spirals upward into an ellipse, and insects are piled with brown worms. Add 1 kg of kerosene and 0.1 kg of 80% dichlorvos emulsifiable concentrate to the insects and kill their larvae. (3) Pear stem bee: one generation occurred in 1 year. The female adult saws and lays eggs in the phloem of young shoots in the middle and mid-April of April. After using its jagged ovipositor, it saws the upper part of the spawning site and the larvae hatch. Food damage, down to two-year-old branches, and settled in winter. When cutting in winter, cut the broken piles, pay attention to cut to the branches of the three-year-old, concentrated burning. (4) Grape-winged moth: It is the main pest of the grape. It occurs one year after birth and is damaged by the larvae, which affect the growth of the branches and the development of the fruit. Both wormholes and wormholes have brown worms. After eating the pith, the vines often enlarge and become tumorous and overwinter. When cutting in winter, remove swelling stems and concentrate. For coarser vines, 80% of dichlorvos can be tapped into the borings with cotton to eliminate larvae.
