When the cornfield plant is infested in the corn field, it is usually necessary to use a large amount of medicine frequently to control the amount of insects. In recent years, accidents caused by improper use of drugs in the production of corn have caused frequent occurrence of accidents. Therefore, safe medication should be taken care of when controlling SBPH.
When using organic phosphorus and pyrethroid pesticides in corn fields to control SBPH, the chemical concentration should be strictly controlled, otherwise it is easy to produce phytotoxicity. For example, 48% chlorpyrifos emulsifiable concentrate is generally used for 2000 times, and the dilution ratio can not be less than 1000 times; pyrethroid pesticides are generally used for 2000 to 3000 times. Dichlorvos, phoxim and fenvalerate are prone to phytotoxicity on corn and are generally not to be used.
Hydroponics is a subset of hydroculture, the method of growing plants without soil, using mineral nutrient solutions in a water solvent. Terrestrial plants may be grown with only their roots exposed to the mineral solution, or the roots may be supported by an inert medium, such as perlite or gravel. The nutrients in hydroponics can come from an array of different sources; these can include but are not limited to waste from fish waste, duck manure, or normal nutrients.
