Before the soil in the cultivator soil is frozen, the cultivator soil is 20-30 cm in length, so that the insect pests turned over to the ground are frozen or eaten by birds. In combination with irrigation, change the environmental conditions of the soil and reduce the source of overwintering insects.
Curing the old diseased skin using the dormancy period in winter, scraping the rough skin or cracks under the main bifurcation of the fruit tree, and killing the overwintering insect resources such as red spider and scale insect hidden in the rough skin, cracks or cracks in the branches. For the ulcers that have been detected, the lesions are promptly scraped off. When the scrapings are done, plastic films are laid under the trees, the rough old skins that are scraped off, and the sick belts are taken out of the orchard and burned together.
Cut off pests and branches combined with winter pruning (mid-mid-December to early-January), remove pest-carrying worms, diseased, ovum-bearing, and weakly growing branches and bring them out of the park for centralized destruction. During the winter pruning, you must first cut the tree, then cut the diseased tree, and pay attention to the disinfection of the pruning tools (scissors and saws). You can use 75% alcohol solution for treatment. After the pruning of large wounds, it can be used to protect 1.6% thiflumone cream, 2.4% humic acid copper sulfate, and artificial bark.
After the pruning of clean fields, we must promptly cut off the dead branches, pests and nuts, remaining bags, and other debris, fallen leaves, scraped rough old cracks, diseases and insects, weeds, and fruit droppings. For pests and diseases, provide items for overwintering sites, thoroughly clear out the orchards, and burn them in a centralized manner to eliminate the sources of overwintering diseases and pests that hide them.
After the pharmacy controls the pruning of the fruit trees, the whole tree is sprayed 1-2 times to protect the wounds after defoliation and pruning. The medicines with high efficiency and low toxicity are selected such as myclobutanil + chlorpyrifos, copper hydroxide, lime sulfur, etc. Used alternately to kill germs and overwintering pests on trees.
Non-Inactivated Disposable Virus Sampling Tube
This disposable Non-Inactivated virus sampling tube is an upgrade from the Hank's solution. Additional various components, such as BSA, HEPES, amino acids, cryoprotectant, etc., are added to enhance the virus integrity. It can be used for nucleic acid extraction of virus, mvcoplasma chlamydia and ureaplasma samples and later virus isolation.
This disposable non-inactivated virus sampling tube consists of fibrous swab and culture medium.The medium contains antibiotics and antimycotics for the purpose of inhabitation of bacteria and veasts overgrowth. It helps to maintain the cellular integrity and preserve the viruses, mycoplasma, chlamydiae and ureaplasma.
When collect specimens with this disposable Non-inactivated virus sampling tube, tube can be transported to the laboratory at 2-8ºC within 2 days. If it can not be delivered to the laboratory within 48hours, it should be stored at-70ºC or below, and ensure that the collected specimens are delivered to the laboratory within 1 week. Avoid repeated freeze-thaw cycles. For best performance, complete testing within 24 hours.
