Where to buy slices, slice while fresh and dry.8 Prevention and control of harmful ThSee Appendix A and Appendix B for control of white and major diseases and insect pests. Combined with land preparation and cultivating, weeding by hand.9 File managementBasic data, production management data, etc. must be created and kept by a special person, and kept for a long time. File management system. 9.1 Basic information Source of mango fruit, harvest batch, time, processing method, conditions and time, etc .; fertilization type, application amount, frequency; reserved seed The types, application methods, time, and frequency of plant disease and pest control; and various other agricultural management measures for retaining plants Fine production records 9.2 Th Property Management 9.2.1 Nursery Management Capsule amount, cultivation time, cultivation management, seedling refining, nursery conditions, planting time, survival rate after planting, etc. 9.2.2 Undergrowth Management Planting time, planting method, survival rate of planted seedlings; types and frequency of fertilization, time and amount of fertilization after planting; pesticides Use type, concentration, frequency, control object and application method; weeding method, time and other agricultural operation measures.Appendix A(Informative appendix) Control methods for white and major diseases A.1 Major diseases A.1.1 Soft rot In the early stage of disease, use 72% agricultural streptomycin sulfate 3000-4000 times solution, or 90% neophytemycin 4000 times Liquid, spray once every 7 to 10 days, then spray 2 to 3 times, and spray. A.1.2 Black spot At the beginning of the onset, use 500% to 1000 times of 75% chlorothalonil wettable powder, or 50% carbendazim wettable powder 1000 times solution, spray once every 7 to 10 days, spray 2 to 3 times, spray A.1.3 Leaf spot gray mold Remove the diseased plant residues, remove the lower diseased leaves at the early stage of the disease; timely take the medicine for prevention. The following agents can be used in rotation. 50% polybacteria Ling wettable powder 500-600 times liquid, 75% chlorothalonil wettable powder 600-800 times liquid, 65% Daisen zinc wettable powder 400-500 times liquid spraying. A.1.4 Root rot For this disease, prevention is the main method, and there is no cure effect after the onset. Prevention. Excessive rain is the main condition for disease epidemic In the years when the rainfall is early and heavy, the incidence is early and severe. Conditions such as low-lying stagnant water, poor ventilation, insufficient light, and improper fertilizer and water are conducive to the onset of disease. Seedbeds should pay attention to ventilation and drainage, increase soil permeability, enrich ecological diversity, and avoid root rot.Appendix B(Informative appendix) White and main pest control methods B.1 The mollusk control methods are. -Sprinkle lime around the salamander to prevent snails and salamander from climbing into the salamander; -Trap with vegetable leaves or grass bait. Use 100% of polyacetal or 40% phoxim EC (mass ratio ) Vegetable leaves or grasses are mixed with wet and sprinkled around the loquat in the evening to lure them. B.2 The main methods of underground pest control are. -Use black light to trap and kill adults. A container containing insects is placed under the lamp, which contains an appropriate amount of water, and a little kerosene is dripped into the water; -Trap with poison bait. Cut fresh grass into 3cm ~ 4cm length, add 50 times with 50% phoxim emulsifiable concentrate (mass ratio ) Wet the fresh grass and sprinkle it around the cricket in the evening to lure in. B.3 Requirements for pesticide use -Confirm that the label is clear and the pesticide registration certificate number and pesticide production license number are complete; -Apply pesticides in accordance with the dosage, product to be controlled, method of use, application period, and precautions specified on the product label; -Rotate pesticides to reduce resistance. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of LY/T 3093-2019_English be delivered?Answer: Upon your order, we will start to translate LY/T 3093-2019_English as soon as possible, and keep you informed of the progress.
