In the Yuli County of Bayingolin Mongol Autonomous Prefecture, Xinjiang, the leaves of cotton reflect a bright, shiny light. Countless locust climbs on top of the cotton seedlings, secreting a layer of oily liquid. The cotton fields here are suffering from insect pests. The locusts suck the sap of the cotton and affect the normal growth of the cotton, causing the cotton to fail to boll normally.
Causes of pest outbreaks
Agricultural technicians are troubled with this year’s cotton condition
This year, the outbreak of plant diseases and insect pests in Xinjiang was the epitome of the cotton field. Last year’s El Niño was the cause of this pest. In 2015, due to the El Nino phenomenon, extreme weather occurred in Xinjiang, and the highest temperature in a month continued to exceed 40 degrees Celsius. According to Li Lin, an agricultural technician, the occurrence of diseases and pests is divided into years and years. The high temperatures in the previous year will increase the base number of overwintering diseases in winter and decrease the wintering death rate, which will, in turn, lead to an increase in pest and disease conditions in the second year.
To this end, Xinjiang Uygur Autonomous Region Plant Protection Station released the warning of pest and disease trends for the following year at the end of 2015, informing farmers that there will be moderate to severe pests and diseases in 2016. Sure enough, the outbreak of diseases and insect pests in various regions of Xinjiang this year has been concentrated and the situation of prevention and control is very severe.
New Challenges for cotton fields
Recently, due to the effects of low temperature in spring and recent precipitation, the effect of pesticides has been greatly reduced, and the control of pests and diseases has worsened. In the vast territory of Yuli County, whether it is crop dusting or tractor application the effect is not obvious. According to result in these periods, Li Lin concluded: “Now the temperature is low, which affects the effectiveness of pesticides. We have played a lot of drugs, but we cannot guarantee the eradication of it.”

Under normal circumstances, Xinjiang’s cotton only needs to spray five times a year. However, this year, the situation in the cotton field is worrying. Li Lin said: “It is possible to spray once every ten days or every half months from May to August.” When talking about this, he feels helpless: “At present, it seems that it is necessary to continue applying the pesticide in the field. If the situation does not improve, then it is necessary to come up with a new solution.

Li Lin frankly stated that many farmers will only understand how to plant and do not understand the needs and control of pests and diseases. Apart from the spraying, Li Lin will recommend some highly effective and low-cost pharmaceuticals to farmers and provide some knowledge of pest and disease prevention so that farmers can use them together with UAV Application. Li Lin said: “After all, most farmers’ life hood relies on the crops in the field. They are anxious and We also want to help.”
Practical Tips (China)
In May, the southern Xinjiang cotton was in the seedling stage. The main pests and diseases were cotton thrips, ground tigers and aphids. During this period, attention was paid to prevention work and the incidence of headless cotton in the later period was reduced. It is recommended to use 2.5% lambda-cyhalothrin 35-40 ml/mu foliar spray, or 20% acetamiprid 15-20 g/mu foliar spray.
From June to July, during this period, the temperature rose and the outbreak of locusts was serious. Prevention was the main priority and attention was paid to the prevention and control of locusts. Foliar spray control can be performed using 40% acetamiprid 15-20 g/mu foliar spray, or 40% acetamiprid 15 g+70% imidacloprid 10 g/mu.
From the middle of July to the beginning of September, this period is the main growth period of cotton plants. The main prevention and control work for cotton aphid and cotton leafhoppers can be done. 70% imidacloprid 10g/mu +1.8% abamectin 40g/mu +24 can be used. % spirulina 10g/mu foliar spray.
After hitting the top in mid-July and before cotton harvesting, the damage of the locusts gradually decreased, and the control of pests and diseases was mainly to cotton leafhoppers and cotton bollworms. Use 1.8% abamectin 40g/mu +73% propargite 35g/mu +40% chlorpyrifos 30g/mu for control, or use 3% abamectin 25g/mu + 20% triazotin 25g/mu +3 billion PIB/ml polyhedrosis virus 25-30 ml/mu for control.
Crops are growing taller, and it is easy to overwhelm crops with traditional tractors. Many farmers have started to choose drones to fight drugs. With the advent of the busy farming season, a red P20 V2 is flying over vast fields.
