Control method: use 5% aldicarb (iron-killing) granules for 3 kg or 15% aldicarb granules 1 kg or 10% gram phosphorus granules for 3 kg per 667 square meters, etc. Fine soil (sand) 5~10 kg is mixed and planted around the seeds, which is safe for the seeds and has obvious control effect. At the same time, it also treats a variety of pests such as golden tortoise shells, aphids and thrips, which feed on the roots of the kernels, roots, and stems and leaves.
The main method for the prevention and control of peanut bacterial wilt, sowing the peanut variety Luhua No. 3 with high resistance to bacterial wilt, can basically control the occurrence of diseases.
Peanut stem rot is commonly known as rickets, and peanut black mold is commonly known as crown rot. Both of these diseases are infested by fungi and the seeds are contaminated. Control method: banned seed seeding. Seeds used for seeding are not moldy at any point in the process of harvesting, drying and storage. If the seed is "smashed", it can be seeded with 50% carbendazim WP at a seed rate of 0.3%, and the effect is remarkable.
For the pest control method, 35% seed coating agent can be used for 2% seed dressing according to the seed amount, or combined with peanut seeding, 10% phosgene (812) powder granule 0.5 kg per 667 square meters, or 3%. 2 kg of methyl isoflavone granules, or 2 kg of 5% carbamide granules, such as systemic, contact, stomach and other effects, directly or finely mixed with fine soil (sand) 5~10 kg Back cover species. It is safe for peanut kernels, rooting, germination, emergence and growth.
For the control of locusts, if the above-mentioned agents are not used to control root-knot nematode disease or mites, or for fields with poor control after application, when the amount of psyllium is found to be 1000, 50% methylamine should be sprayed in time. Phosphorus EC 1000~1500 times liquid, or 20% Guangkewei EC 1500~2000 times liquid, or 40% omethoate EC 800~1000 times liquid and other chemicals.

Zhejiang Sealand Technology Co., Ltd. is a trustworthy manufacturer of Alcohol Mass Flow Meter, Alcohol Mass Flowmeter, Alcohol Coriolis Meter, Mass Flow Meter Alcohol, Coriolis Mass Meter Alcohol, ATEX, IECEx & CE approved.
Sealand meter is designed and produced according to world`s latest Coriolis technology with better appearance, stability and accuracy to measure mass flow rate of a fluid traveling through a tube, widely applied to alternative energy, oil & gas, chemical, food & beverage, industrial energy, marine, power, pulp & paper, water & wastewater industries, etc.
Mass flow meter measures the mass based on Coriolis effort. The operating principle involves inducing a vibration of the tube through which the fluid passes. The vibration, though not completely circular, provides the rotating reference frame that gives rise to the Coriolis effect. While specific methods vary according to the design of the flow meter, sensors monitor and analyze changes in frequency, phase shift & amplitude of the vibrating flow tubes. The changes observed represent the mass flow rate and density of the fluid.
