Cypermethrin
It is a synthetic pyrethroid used as an insecticide in large-scale commercial agricultural applications as
well as in consumer products for domestic purposes. It behaves as a fast-acting neurotoxin in insects. It is easily degraded on soil and plants but can be
effective for weeks when applied to indoor inert surfaces. Exposure to
sunlight, water and oxygen will accelerate its decomposition. Cypermethrin is
highly toxic to fish, bees and aquatic insects, according to the National
Pesticides Telecommunications Network (NPTN). It is found in many household ant and cockroach killers,
including Raid and ant chalk.

The main field is weeding soil, mainly by manually removing weeds. To promote ginger root elongation and improve quality, cultivating soil 3-4 times according to growth conditions. When the ginger begins to give birth, the first weeding is performed and the soil is treated with fertilizer and water several times. The earth is made by digging the earth. After each earthing, the ditch is deepened at the same time, which is also conducive to drainage and ventilation. Ginger growth requires a moist environment, but it is also very fragile. Therefore, the cultivator should combine clean trenches. Do not stop the rain and there is no stagnant water in the field.
Agricultural
Ginger needs a large amount of fertilizer, in addition to applying base fertilizer, fertilizer should be timely. The germination period does not require top dressing. The height of the seedling is 30 cm, the seedling fertilizer is recovered once for 1-2 branches, and the application of ammonium sulfate or diammonium phosphate is 20 kg, or the potassium sulfate compound fertilizer is 30 kg. To recover the fertilizer, 75 kg of Mushi cake fertilizer and 50 kg of compound fertilizer were combined with the topdressing soil for the first time. After that, the first and second soils were combined with watering. If there is more rain, you can put each chemical fertilizer on the side of ginger nest, 50-100 grams per plant, when it is raining.
