Embodiment 1

[0023] A method for preventing and treating diseases and insect pests in tribute orange orchards, the steps are:

[0024] Clear the garden in time: after fruit picking, use 120 times of 29% lime sulfur aqua, or 300 times of 45% lime sulfur crystal, or 150 times of engine oil emulsion + 1500 times of propargite, spray the tree crown and the ground 1 or 2 times; Cut off the strong branches, keep the middle and weak branches, cut off the dead, diseased and leafless branches, and cut off the excessively high branches and too low drooping branches, and cut off the excessively high branches and too low drooping branches, and try to make the tree shape as good as possible. Ensure the reasonable distribution of nutrients to each branch and leaf of the fruit tree, so that the growth of the whole fruit tree is balanced, because winter pruning can cut off a large number of diseased and dead branches, which is also one of the most effective measures to comprehensively reduce the overwinter...

Embodiment 2

[0031] The difference from Example 1 is that the amount of the medicament used is: 180 times of 29% lime sulfur aqua, 500 times of 45% lime sulfur crystal, or 250 times of engine oil emulsion + 2500 times of propargite, 25% of lice Ling wettable powder 1800 times or 2.5% kung fu permethrin emulsifiable oil 3500 times.

[0032] Through the method of the above embodiment 2, the amount of diseases and insect pests in tribute mandarin oranges is greatly reduced; wherein, compared with the traditional method, leaf miners are reduced by 39%, psyllids are reduced by 30%, aphids are reduced by 43%, spiders are reduced by 59%, and rust spiders are reduced 34%, 50% reduction in rust ticks, 49% reduction in scale insects, and 68% reduction in beetles.
