Summer-sown corn pests are high-rising to boost the market for pesticides

At present, it is the emergence period of summer-sown corn. This year due to special climatic reasons, the early drought and high temperature, and the recent continuous low temperature and low temperature, coupled with pests such as the two-pointed moth, second-generation armyworm, scorpion worm, gray planthopper, etc. Serious occurrence has led to the phenomenon of uneven emergence, lack of seedlings and ridges in many plots of corn. According to farmers, there are many pests in the ground this year. Many corn seeds have not yet germinated, and they have been bitten by the golden worms in the underground. There are also many newly unearthed corn seedlings that have been cut off by the sericulture, and others are endangered by cockroaches. The heart of the corn seedlings is rolled into a whip, not unfolded, like a twist, or the symptoms of heart leaf rot.

The high incidence of summer-sown corn pests has driven the insecticide market to heat up. Many distributors recommend pesticides such as imidacloprid, acetamiprid, chlorpyrifos, and pyrethroids to farmers. Combined with ground spray, they can also be used to control underground pests. Some dealers have written these guidelines on a self-made blackboard to promote the farmers. At present, the strong sales of the insecticide market in the summer maize area is in stark contrast to the downturn in the northern grassroots pesticide market in the first half of this year.

Affected by prolonged drought and little rain in spring, this year's pesticide market has not moved. As for the author's Wulian County in Shandong Province, in the past years, the farmers in the wheat field management were controlling wheat stubble, red spider, and midge, and at least two times of drug control, which would lead to imidacloprid, acetamiprid, and cyhalothrin. The warming of the insecticide market, while farmers combined with the prevention and control of wheat powdery mildew, stripe rust, smut, etc. can also promote the popularization of fungicides such as triadimefon, tebuconazole and carbendazim. However, the long-term drought in spring this year has caused many farmers to abandon the management of wheat fields, and the use of drugs is rare, leading to the sluggish market of pesticides. In addition, in many areas, due to less precipitation, poor sensation, delayed planting of spring peanuts, and limited use of the entire pesticide market. By the beginning of June , winter wheat entered the harvest period, but due to poor grievances, farmers could not plant properly, and they had to wait for rain. In recent years, due to the large-scale occurrence of corn rough disease, many media and agricultural experts have also suggested that farmers not only strengthen the control measures against Laodelphax striatellus, but also avoid the nesting and timely extension of the planting, thus delaying the pesticide market. It can be said that the entire pesticide market has been in a downturn from peanut seeding to winter wheat harvesting.

Until June 17, the northern most areas usher in a wide range of rainfall, farmers began to rob moisture in planting summer corn and soybeans, the pesticide market began to enter the sales season, mainly acetochlor, the herbicide paraquat or special corn field. Many farmers are accustomed to using acetochlor and paraquat to blend together, and also use pesticides together to prevent and control all kinds of pests, which also effectively promotes the sales of pesticides. The drugs recommended by dealers mainly to farmers are like This method is worthy of recognition for phoxim, methylisophosphorus, chlorpyrifos and so on. However, farmers should be told that when using cornfield-specific herbicides such as nicosulfuron and atrazine, organophosphorus and carbamate pesticides should not be mixed, and the safety interval should be more than 7 days.

A village-level dealer in the street town of Wulian County reported that these days sales were ideal, and farmers were busy fighting drugs. The products he recommended to farmers mainly were acetamiprid, imidacloprid and chlorpyrifos. The sales price was mainly stable. Many pesticide varieties still maintain last year's retail price, such as acetamiprid / bottle ( 100ml ), retail price of 10 yuan, Xin·chlorpyrifos / bottle ( 300ml ), retail price of 8 yuan. Only a few varieties have risen, such as dichlorvos, methyl isophosphorus, etc., each box rose by 10 to 15 yuan, retail prices rose by 1 yuan per bottle , the relative sales of such pesticides is relatively small, farmers can also recognize.

In short, with the serious occurrence of summer-sown corn pests in the recent period, the market for pesticides and pesticides has finally been boosted, and the downturn in the insecticide market in the first half of the year has changed, ushered in a peak in drug use. Li Jinqin
