Field efficacy test of Metarhizium anisopliae CQMa421 against rice planthopper

8 billion spores/mL of Metarhizium anisopliae CQMa421 dispersible oil suspension agent 1350mL/hm2 has good control effect on rice planthopper. The effective period is long. The average control effect is more than 85% 14 days after the treatment, but it is significantly lower than the corrected control effect of the control agent 25% pirimid suspension agent 450 mL/hm2 91.9%. 8 billion spores/mL of Metarhizium anisopliae CQMa421 dispersible oil suspension agent is safe for the growth of rice, and has no effect on the number of dominant natural enemies such as spiders and cocoon bees in the field.

Field application effect of Metarhizium anisopliae CQMa421 on controlling tea horned chest beetle

The suspension agent of Metarhizium anisopliae CQ ⁃ Ma421 had significant control effect on wheat spike aphid and wheat sheath blight, 88.6% and 89.4% respectively, and had certain control effect on wheat stripe rust, and the control effect reached 31.6% in the final investigation. At the same time, it has obvious effect of increasing yield, increasing seed setting rate by 5.3% and increasing yield by more than 20%. It is worth popularizing and applying in places where wheat aphids occur heavily.

Effects of Metarhizium anisopliae 421 mixed with reduced chemical pesticides on the control effect and yield of Spodoptera glutinosa on summer maize grassland

In this paper, the effects of mixed use of Metarhizium anisopliae 421 and reduced chemical pesticides on the control effect and yield of Spodoptera glutinosa on summer sown corn grassland were explored, providing scientific basis for the high-quality and efficient control of Spodoptera glutinosa in the corn industry. From 2019 to 2020, through the investigation and research on the occurrence and harm of Spodoptera exigua in Pu'er City, and the field drug comparative efficacy test of a variety of insecticidal fungal pesticides and chemical pesticides against Spodoptera exigua was conducted. In the test, there were generally high safety of insecticidal fungal pesticides, which were not easy to produce resistance, but lack of quick-acting, while chemical pesticides had good quick-acting, and long-term use produced resistance.
