Management of wheat in the middle and late period grasps "one spray and three defenses"

In the middle and late stages of wheat growth, it is a critical period for the formation of yield, and it is also the peak period of various diseases and insect pests. Good management of the field during this period is very important to ensure the high yield of wheat. In recent years, the "one spray and three defenses" technology has been widely used in the mid and late management of wheat. It refers to mixing and spraying pesticides, fungicides, trace fertilizers, drought-resistant agents, etc. to achieve the prevention and control of wheat pests and diseases and prevent dry hot winds. The purpose of controlling lodging and increasing grain weight is to increase production and income. In the province, wheat will enter the booting and heading stage one after another from south to north, and “one spray and three defenses” may be carried out, focusing on the control of diseases such as scab and ear blast. Fusarium head blight also known as wheat. Rotten wheat head, red wheat head, wheat are vulnerable from the seedling stage to the heading stage, mainly causing seedlings, stem base rot, culm rot and ear rot, among which the earliest victim is ear rot. Prevention and control of wheat scab, the focus should be on the prevention of wheat heading and flowering. In the initial flowering period, carbendazim, thiophanate-methyl, prochloraz and other drugs were sprayed, and Yongye Lifeline 500 times liquid was sprayed at the same time. Locust seedlings have 30-60 mites per m2 of seedlings to be controlled, and at the booting stage there are 15% of alfalfa strains or an average of 10 mites per plant. You can use imidacloprid, acetamiprid, butyl sulfide, and other drug sprays, and spray Yongye Lifeline 500 times. “One spray and three defenses” time: Wheat booting and heading period: from late April to early May, when the temperature is high and the humidity is high, it is a period of high incidence of diseases and insect pests. Wheat filling period: in mid-late and late May, it is a critical period for yield formation. Spraying foliar fertilizer in combination with pest control can prevent dry hot air and increase grain weight. The following points should be taken into account when adopting the “one spray and three defenses” technology: 1. The use of highly toxic and high residue pesticides is strictly prohibited. 2. According to the occurrence characteristics and occurrence trend of pests and diseases, choose suitable pesticides, scientific formulas, and even spray. 3. Spraying wheat during heading and flowering period should avoid flowering pollination period. 4. Strictly abide by the safety procedures for the use of pesticides, do a good job of protection, prevent poisoning of personnel, and do a good job in cleaning the pesticide application equipment. Yongye Lifeline's use on wheat: Seed dressing method: Use Yongye Lifeline 70-100 milliliters to add 1.5 kilograms of water and 30 kilograms of seed, then boring for 2 hours, spread out to dry and sow. The use of Wing Yee bios seed dressing can increase the germination rate of wheat, ensure uniform germination and sprouting, and increase seed disease resistance. Foliar application period and use effect: Spraying Yongye Lifeline 500 times in the jointing stage of wheat can prevent lodging and promote plant growth and robustness. Spraying Yongye Lifeline 500 times solution at the booting stage can promote the heading of wheat and enhance the plant's ability to resist disease and lodging, so that the wheat plants can grow robustly and increase the panicle length. Spraying Yongye Lifeline 500 times at the initial stage of grouting can enhance the plant's resistance to lodging and resistance to dry hot wind, promote grain filling and increase grain weight.
