In the clearing of the garden, the high-temperature composting in a place far away from the orange orchard can eliminate many pathogens and pests that overwinter in these places. Therefore, in winter, winter pruning should be combined to remove diseased branches, dig out dead trees, and eradicate weeds. At the same time, scrape off the moss, lichen, etc. on the trunk to eliminate overwintering pests and places on the tree.
Cultivation loose soil, like flower bud maggots and other pests, generally live in the soil as larvae, and fruit flies and geometrids live in the soil as pupae. Therefore, deep plowing of the garden soil during the overwintering period can cause mechanical damage to the larvae and pupae of pests such as fruit flies, flower bud maggots, or death due to environmental discomfort, effectively reducing the insect population of the orange garden in the coming year.
For whitening, first sweep the stems and branches that need to be whitened, and then perform whitening. If the tree trunk has large cracks, or there are tree holes or wormholes in the tree, use cement, or use fine river sand, or use fresh cow dung, lime, yellow mud mixture, etc. to block the wormhole. You can also use absorbent cotton dipped in 80% dichlorvos emulsion, or 5-10 times of 40% dimethoate EC, stuffing it into the worm hole and then blocking it, the insect removal effect will be better.
Drug prevention and treatment If the orange tree bark tissue that is deadly infected with resin disease is found, the diseased part should be scraped off, and the wound can be disinfected with 75% of the essence and smeared with medicine. The medicament has 75% carbendazim wettable powder 100 times liquid, or 1% antibacterial agent 402, etc. It can also scrape the lichen and moss growing on the base of the trunk. Scrape foot rot spots, cracked and dead citrus tree bark, in order to apply protective agent.
At the same time, combined with the clearing of citrus gardens, 80-100 times the oil emulsion can be sprayed, and the acaricides such as Quick Cull and Kemite can be added to effectively kill overwintering rust ticks and scale insects. , Red spiders and other pests, but also can control lichen, moss and soot. It is also possible to spray an aqueous solution of lime-sulfur mixture with a degree of 0.6-0.8 Baume on the canopy once or twice in winter.
For orange orchards with serious scale insects, spray 10 times the rosin mixture, but the rosin mixture and lime sulfur mixture should be used more than 15 days apart to prevent phytotoxicity. Sprinkle 5% to 10% tea dry water or lime water , It can effectively kill the larvae of various pests that overwinter in the topsoil layer or soil cracks.
