Is it suitable for spraying pesticides during the flowering period of wheat?
Heading and flowering stage is a key stage affecting wheat production, and it is also an important part of the prevention and control of diseases and pests. However, there has long been a great deal of debate about whether or not to use pesticides during the flowering period. Some people say that spraying pesticides before heading will affect the growth and development of wheat and affect the yield; It is also said that wheat without pesticides will be infested by pests, resulting in reduced or no yield. So, can pesticides be used?
First of all, we need to recognize the characteristics of wheat flowering time. During the period of heading and flowering of wheat, it is a critical period from vegetative growth to reproductive development. At this time, the plant is more susceptible to external influences and is more susceptible to external influences. Therefore, it is necessary to be extra careful at this stage, otherwise it will bring undesirable consequences to the wheat. Why, then, do some people think that pesticides should not be used when wheat is blooming? This is due to the fact that some pesticides can have an undesirable effect on the pollination process of wheat, resulting in incomplete grains and thus reducing its yield. In addition, some pesticides can cause direct damage to crops, causing crop mortality and malnutrition.
At the same time, we should not ignore the damage of pests and diseases of crops. During the heading and flowering stage, pests and diseases such as scab and aphids are very easy to take advantage of the situation, bringing huge economic losses to wheat production. During this period, if there is no effective control of pests and diseases, it will lead to a significant decline in yield, and even no harvest of grains. Therefore, how can we ensure the normal production of crops and the healthy development of crops? The first step is to choose an insecticide that does little or no harm to the wheat. In addition, in the process of using the agent, it is necessary to pay close attention to the climate and soil conditions, and avoid using it in high temperature, drought and rainy days, otherwise it will bring adverse consequences to wheat. On this basis, it is necessary to control the timing and methods scientifically and reasonably according to the pathogenesis and characteristics of pests.
Whether pesticides can be used during the flowering period depends on the specific environment. Only by making scientific and reasonable selections can we better control the pests and diseases of crops and ensure the production and quality of crops. In order to ensure the normal production of crops and increase yields, it is necessary to fully understand their flowering characteristics and the pathogenesis of major pests. On this basis, it is necessary to increase investment in science and technology for peasant households, increase their understanding of scientific and technological planting, enhance their ability to prevent and control pests and diseases, and lay a solid foundation for promoting the sustainable development of the rural economy.
