Imidacloprid and triadimefon should be suitable as the concentration of wheat seed coating

In order to investigate the appropriate amount of imidacloprid and triadimefon as wheat seed coating, to provide a reference for the safe production of wheat, Henan University of Science and Technology Institute of Plant Protection Department of Forestry researchers at 70,11,06156, 18 and 11 weeks wheat spike 136 wheat varieties ( The germination test of indoor culture dish was carried out for the material. The effects of different concentrations of 50% imidacloprid wettable powder and 25% triadimefon wettable powder on wheat seed germination were studied.

The results showed that different concentrations of 50% imidacloprid wettable powder and 25% triazolone wettable powder had different effects on the germination rate, germination potential and germination index of five wheat varieties (lines). When 50% imidacloprid wettable powder and 25% triazolone wettable powder were 125.0 mg/L and 75.0 mg/L, respectively, the germination rate, germination potential and germination index of the five wheat varieties (lines) were the highest. And it has obvious promoting effect on seed germination, and can effectively isolate pests and diseases, and ensure the normal and safe germination of seeds. Above this concentration, the germination rate, germination potential and germination index of wheat seeds are reduced.

Panels can be used as portable or permanent fencing. Using our safe and strong clamp system for panel attachment.
Our steel corral panels, as the strongest, most affordable products on the market can work for you whenever you need them. Compared with aluminum corral panels, this one is made of high tensile strength steel tubing with superior full welded saddle joints. Therefore, it's strong enough to withstand years of abuse. Meanwhile, all the products are galvanized or color painted after welding to protect the panel from rust and corrosion. Portable steel panels are easy to set up only by one person.
