Timing for controlling excessive growth in sesame: does the 4-6 leaf stage work?
Abstract: The time to control excessive growth in sesame is during the full fruiting stage, during which the terminal bud at the top can be removed. If the planting area is relatively large, mepiquat chloride or chlormequat can be sprayed during the full fruiting stage to control excessive growth. During the seedling stage of sesame, diluted decomposed human excrement or urea can be applied as a top dressing; at the

What are the control methods for wheat sharp eyespot?
Abstract Wheat sharp eyespot is mainly controlled by an integrated approach combining chemical control with agricultural measures. At sowing time, varieties with relatively good disease resistance should be selected, and a single resistance-source variety should not be planted over a large area. Before sowing, seed treatment can be carried out with fludioxonil suspension concentrate, tebuconazole suspension seed dressing, or triadimefon wettable powder. During the growing period, nitrogen, phosphorus and potassium fertilizers should be applied rationally to improve the disease resistance of wheat. After entering the jointing stage, difenoconazole·propiconazole emulsifiable concentrate can be used in appropriate amounts.
