What's the difference between traditional pesticides and new pesticides?

The main differences between traditional pesticides and new pesticides are:

1, activity and toxicity of the original drug. Traditional pesticides are generally toxic, low in activity, large in dosage and have a great impact on the environment; New pesticides generally have high activity, low toxicity, small dosage per mu and relatively little impact on the environment;

2. Differences in pesticide formulations. Traditional pesticides generally use traditional formulations such as emulsifiable concentrate and wettable powder, which have the disadvantages of using a lot of aromatic solvents and large dust, and have a great impact on the environment and users. New pesticides generally adopt water-based dosage forms, reducing or not using aromatic solvents and increasing environmental compatibility.
