In November 2018, I received some plants in very poor condition. I decided to do an experiment. Plants received azoxystrobin at a concentration of 3 mg per liter 1 time per month spraying and watering with this solution. Application 3-4 times per season. I did not use Scotts Disease-Ex Lawn. In my country, another form of azoxystrobin is available.
Growth was very fast. Several months later, the plants reached adult size and had a flower stem. But at the end of summer, I noticed that some of them have too long leaves. This does not belong to the characteristics for these clones. Then I thought that maybe this is due to the fact that plants have little living space. It was pretty cramped for growth. Then the plants received a rest period of 3 months at a temperature of 3-15 degrees Celsius. In the spring everyone repot in big pots. Some also received azoxystrobin in February and March. And again, I see that some have long leaves that are not inherent in these clones at this time in the spring. It may seem that plants do not have enough light. But this is not so. They have 5-6 hours of the sun (of course when it is) and additionally lighting with professional bulb grow ligth. They have these traps: In the control group, some plants did not receive azoxystrobin in 2020.
For comparison, some clones with and without the use of azoxystrobin. Maybe surveillance to continue 1.5 years is not enough. Maybe observing 10+ clones is not enough. May be.
But I will not use use azoxystrobin for full-grown plants.
This is good for small weak plants to accelerate their growth and maturation. But completely redundant for healthy adult plants.
