Methods and compositions relating to applying a herbicidally effective amount of a composition comprising chelated mesotrione on a HPPD tolerant soybean crop are disclosed.

The invention provides application of a chelated fertilizer nutritional agent capable of simultaneously supplementing calcium and boron elements in capsicum, tomato and soybean crops, and belongs to the technical field of agriculture. The chelated fertilizer nutritional agent is applied to crop leaf surfaces, the fertilization interval is 10 days, and the fertilizer-water ratio of each time of fertilization is 1: 500. The product is in a brand-new plant calcium and boron supplement chelated state, is capable of increasing yield, high in quality, remarkable in effect, capable of being quickly attached to leaf and stem surfaces of crops, not prone to evaporation, high in component utilization rate and extremely easy to absorb and utilize by the crops. Healthy growth of nutritional organs and reproductive organs of crops can be promoted, and plant metabolism can be participated; flowering, fruiting and root development of plants can be promoted, and the yield and weight of a seed-fruit field are improved; the pollination rate and the fertilization rate of crops are improved, empty pods, empty buds, shrunk fruits and small fruits of fruits are reduced, and the fruits are prevented from becoming early and falling off; the quality and yield of the fruits are improved, and economic losses caused by lack of boron and calcium are supplemented to crops in time.
