and observing whether the chemical has phytotoxicity to cotton or not 20 days and 30 days after the chemical is applied, and recording the type and degree of the phytotoxicity. Recorded as follows:
a) If phytotoxicity can be counted or measured, absolute values are used, such as plant number or plant height, etc.
b) In other cases, the extent and frequency of phytotoxicity can be estimated in two ways:
1) Grading the phytotoxicity of each cell according to a phytotoxicity grading method:
stage 1: cotton grows normally without any victim symptoms;
2 stages: cotton is slightly phytotoxicity, and the phytotoxicity is less than 10%;
3 stages: the chemical injury of cotton and the like can be recovered later, and the yield is not affected;
4 stages: the cotton has heavy phytotoxicity and is difficult to recover, so that the yield is reduced;
5 stages: the cotton has serious phytotoxicity and cannot be recovered, so that the yield is obviously reduced or is absolute.
2) The drug treated area was compared with the blank control area and the percent phytotoxicity was evaluated.
Accurately describes the symptoms (growth inhibition, fading, dead spots, deformity, etc.) of cotton phytotoxicity. The growth of cotton was recorded in all cases. And observing the interaction between the phytotoxicity and adverse factors (such as damage caused by cultivation methods, lodging, insect pest invasion, long-term high temperature or freezing injury and the like).
