Embodiment 1
[0019] Example 1: Indoor Toxicity Determination of Thiram, Cyclostrobin, Aminooligosaccharin and Mixtures to Rice Blight
[0020] Test object: Rice blight (Rhizoctonia solani), collected from the field, separated and purified indoors.
[0021] Test method: After pre-testing to determine the effective inhibitory concentration range of each agent, dilute thiram, cyclostrobin, amino oligosaccharin and their mixed preparations to 5 concentrations in series according to the gradient of active ingredient content, and use sterile water as a control . Refer to the "People's Republic of China Agricultural Industry Standard NY / T1156.2-2006", and use the mycelium growth rate method to determine. Add different concentrations of medicines into sterilized petri dishes, 1mL per dish, then add 10mL of sterilized and melted PDA medium, mix thoroughly to form a plate, and then punch the expanded colony into a 0.8cm bacterial dish, 1 per dish The slices were repeated 4 times for each treatment...
Embodiment 2
[0031] Example 2: 5% thiram · 3% cyclostrobin · 2% aminooligosaccharin suspension seed coating
[0032] The content of each component (by weight) is: thiram 5%, cyclostrobin 3%, amino oligosaccharin 2%, agricultural milk 6022%, sodium lignosulfonate 5%, quinone 2%, xanthan gum 0.5%, silicone oil 1%, urea 2%, basic rhodamine 0.6%, add water to make up to 100%. After mixing, grind in a sand mill for 3-4 hours, so that the particle size is all below 5 μm.
Embodiment 3
[0033] Example 3: 6% thiram · 5% cyclostrobin · 2% aminooligosaccharin suspension seed coating
