At the same time, photosynthesis in the leaves is reduced, affecting production. They are usually found in closely packed colonies [...] through the crop by walking. The tobacco aphid tends to form denser colonies, closer to the top of the plant, than the peach potato aphid . It is not known

  Aphidius species Controlling Myzus persicae in the crop has become increasingly challenging in recent years. In response, Koppert has conducted extensive [...] indicates that the parasitic wasp Aphidius matricariae is a more effective agent for the control of M. persicae to Aphidius colemani, especially in cooler t [...] temperatures. However, in high-temperature greenhouse environments, Aphidius colemani remains the top choice. Difference in performance between Aphidius

We used the same dosage of Enermix in the three test [...] although the level of infestation is lower, he will also apply Mycotal in the unlit crops this year. Improved Mycotal still the best product In recent years [...] of infestation is higher and whitefly levels are high earlier in the year.
