Pesticide spraying is not the more concentrated the more effective

In the process of crop growth, spraying pesticides is an indispensable process, because the use of pesticides can solve most of the problems of diseases, insects and weeds. However, if the amount of pesticides is not well controlled when spraying pesticides, then the original intention of protecting crops is the last one. It became hurt. The reporter recently learned that Wei, a villager in Bachu County, planted 300 acres of wolfberry. In order to sterilize, kill insects, and kill mites, Wei purchased a lime sulfur mixture, but after spraying it, the wolfberry could not bloom normally. In order to find out the cause and loss, Wei found Xinjiang Zhenguanda Agricultural Technology Co., Ltd. for agricultural technology appraisal.

According to Wei, in mid-March, he bought lime sulfur mixture somewhere in Tu and sprayed it at the concentration of 1:6. After using it on goji berries, he found that goji berries could not bloom normally. The company’s agronomist Zheng Zhiqiang Means: Wei's wolfberry does not sprout as a whole, and the self-sealing does not extend. This phenomenon occurred due to the use of high-concentration lime sulfur mixture during this period, which caused the pruning part to absorb a large amount of high-concentration liquid medicine to cause phytotoxicity and inhibit the growth of wolfberry.

Agronomist Shen Tongan reminded growers that Lime Sulfur Mixture is an inorganic sulfur preparation that has the effects of killing bacteria, insects and mites. When the drug is used in orchards, it can effectively improve the quality of orchard orchards and can prevent and treat a variety of fruit tree diseases, but it can still cause great harm if used improperly. Not only the lime-sulfur mixture, but also the concentration of a variety of pesticides are determined according to the weather conditions and control period. The temperature in winter is low and the plants are in a dormant state, so the concentration can be higher. However, the higher the temperature, the higher the efficacy. When the temperature reaches 32℃ or higher, the concentration should be lowered. If the concentration is too high or the temperature is too high, it is easy to cause harm.
