Before the fruit trees sprout in winter and spring before sprouting, all orchards must be sprayed once to kill, eradicate the bactericidal, insecticidal, acaricide. 1 winter and spring, pay attention to alternate medication, spraying should be meticulous, thoughtful, was rain.
The main agents used are:
The practice of spraying lime sulfur for many years has proved that the lime sulfur sprayed with Baume 3 to 5 degrees before the bud is a very ideal Qingyuan pharmaceutical. The drug has a wide range of bactericidal and insecticidal spectrum, and has strong contact toxicity. It can prevent fruit tree powdery mildew, anthracnose, flower rot, scab, black spot, blackpox, brown spot, leaf loin, rust, brown rot Disease, bud blight, and leafhoppers, ticks, scale insects and other pests.
Spraying broad-spectrum, high-efficiency, strong permeability, good touch killing, insecticide, etc. Since most of the fruit orchards have a small area, it is more troublesome to make lime sulfur mixture, and lime sulfur cannot be mixed with pesticides and need to be sprayed separately. The use of insecticides is labor- and time-consuming. As a result, there have been fewer and fewer farmers applying lime-sulfur compounds in recent years, providing opportunities for some broad-spectrum and highly efficient fungicides. At present, the bactericides used in Qingyuan are mostly triazoles, such as propiconazole, tebuconazole, fluorosiliconazole, fluconazole, etc. The pesticides are mainly chlorpyrifos, profenofos, etc. or their organic compounds. preparation.
The concentration of bactericidal and insecticidal agents used in clear gardens is generally high. Therefore, it must be applied before germination of fruit trees to avoid causing phytotoxicity. Http://Content/e501d2b9-05c1-4c06-a579-46488e29473a?cType=2
