What are the commonly used chemical control methods for stored-grain pests?
1. Pirimiphos-methyl: Pirimiphos-methyl is an internationally preferred grain protectant, with the chemical name methyl pyrimidinyl (thio) phosphate, and the usual dose for controlling stored-grain pests is generally 5 ppm. 2. Baolianglin: Baolianglin is a grain protectant developed by the Chengdu Grain Storage Research Institute of the State Administration of Grain, and it has a very good control effect on stored-grain pests, especially suitable for rural grain storage. The ratio of Baolianglin to raw grain is 1:2500. That is, each 100-gram bag of Baolianglin can be mixed with 250 kg of raw grain.

How to Store and Preserve Fresh Peaches? A Detailed Guide to Practical Techniques
I. Cold storage. Peaches are prone to cold injury during low-temperature storage, and there is a risk of freezing at -1°C. Therefore, the suitable storage temperature for peaches is 0°C, and the suitable relative humidity is 90%-95%. Under these storage conditions, peaches can be stored for 3-4 weeks or longer. However, when peaches are stored at low temperature for a long time, the flavor gradually becomes bland. Long-term low-temperature cold storage will cause cold injury to the peaches, with browning of the flesh. In particular, when the peaches are moved to a high-temperature environment for ripening, the flesh becomes dry, mealy, and soft, and the flesh around the pit clearly

Are there other ways to store ginger? An introduction to ginger storage tips
Besides putting ginger in a well, are there other storage methods? Ginger storage techniques: 1) Storage characteristics. Ginger prefers warmth and moisture, is not tolerant of low temperatures, and is prone to cold damage below 10%. Cold-damaged ginger rhizomes rot easily when the temperature rises again; storage temperatures that are too high also cause rot. The suitable temperature is about 15°C, and the relative humidity is 65%. For storage, ginger should be harvested with fully grown rhizomes and must not be exposed to frost in the field. Generally it is put into the cellar for storage immediately after harvest and must not be left in the field overnight. It is best not to harvest on sunny days to avoid excessive sun exposure; ginger harvested in rainy weather or after rain does not store well.

How to store ginger seed stock well? A detailed guide to innovative storage techniques
After harvesting ginger, first spread it out in a ventilated, dry place for a few days; once the surface water on the ginger rhizomes has dried, put them in a storage pit. Before storage, first carry out the following treatments: 1. Disinfect the ginger seed stock by soaking it in a 60% thiophanate-methyl wettable powder solution at 800 times dilution, or soak 600 kg of ginger seed stock using 10 g of sweet potato preservative mixed with 100 jin of water for seed soaking and disinfection; 2. Disinfect and kill insects in the storage pit by spraying the pit with a mixture of 50 g thiophanate-methyl and 30 g kuaishate added to every 15 kg of water. After disinfection is done, place the ginger seed stock into the storage pit, install the exhaust pipe, and seal the pit when the room temperature is below 12°C

What are the methods for keeping garlic scapes fresh? Do this to store them longer
1. Harvesting garlic scapes 1. Harvest at the right time. The suitable harvest period is when the scape stalk has grown out of the terminal leaf and bends to one side (that is, hooks) around in a full circle. Harvested too young, the flavor is poor and it does not keep well; harvested too old, the quality is poor and it has no value for long-term storage. 2. Harvesting method. The "lifting the seedling" method is preferable: hold the scape stalk where it emerges from the terminal leaf with your hand and lift upward, so that the scape stalk breaks off from the base. The cross-sectional wound caused by "lifting the seedling" heals easily, whereas the wound from "cutting the seedling" harvest rots easily. 3. Harvesting time. Choose a sunny day, and by no means harvest on a rainy day.

How to store lotus root? Four practical methods shared
1. Sand storage method: Choose a spot with high terrain, sheltered from wind and rain, spread a layer of fine sand on the ground. The fine sand should have a moisture level such that it forms a ball when squeezed by hand and crumbles when released. Dig drainage ditches around the perimeter. Place a layer of lotus root, then a layer of fine sand, alternating sand and lotus root in this way, stacking 5~6 layers, and cover the top with wet sand about 10 cm thick. This method generally allows storage for about 60 days. Alternatively, you can build a burial pit indoors enclosed by bricks or wooden boards, spread a 5 cm thick layer of wet sand in the pit, arrange the dug-up lotus roots with mud in order, then stack layer by layer, one layer of lotus root and one layer of wet sand, stacking 5~6 layers, and on top
