In the process of citrus growth, it is often attacked by a variety of pests and diseases. The pests and diseases suffered by different growing citrus are also different. Xiaobian summarizes the methods of pest control in each cycle of citrus growth. Let us study together. 1. Citrus meal is in the new shoot stage, the peak period of adult and the peak period of 10~15 days, using buprofezin plus acetamiprid or imidacloprid. 2. The focus of citrus leafhoppers is to reduce the number of insect source bases in February and August, and the peak period from March to June and September to November. The orange orchards with more than 5 leaves per leaf should be sprayed and controlled in time. The control agent may be selected from the group consisting of avermectin, mineral oil, spironolactone, liuyangmycin, thiazolone, and guanidine. 3, ulcer disease focuses on prevention and treatment of young shoots and young fruit. The spring shoots are controlled by the leaves in the greening stage, the summer shoots are 5~7cm in length, and the young fruits are 0.8~1cm in diameter. The second dose is sprayed every 10 days. The medicinal agent may be selected from the group consisting of thiabium copper, Bordeaux liquid (used in the clear garden and spring shoot period), and neutrophin. 4, anthracnose, resin disease when the disease rate reached 5% or acute lesions, should be timely drug control, control agents can be selected with thiophanate-methyl, difenoconazole, mancozeb, prochloraz Wait. 5, citrus leaf miner saplings and early fruit trees in the summer and autumn shoots, adult trees in the autumn shoot prevention, when the tip length 1 ~ 1.5cm application, spray again every 7 to 10 days. The drug may be selected from imidacloprid, acetamiprid or the like. 6, the scale insects from late April to early May, picking the central insect strain; when most of the orange trees have more than 5% of the leaves of the live baby, the whole garden is ruled. The drug may be selected from the group consisting of buprofezin and chlorpyrifos. 7, rust wall è™± 6 ~ July, such as 10% of the fruit surface can be seen or begin to appear sporadic rust fruit, should be timely medication control. The agent can be selected from mancozeb and liuyangmycin.
