Apply for the treatment of durian root rot diseases

The research and test is a study of the results of using G Plus products in combination with Green Plus products, which are microorganisms to eliminate fungi in the soil and improve soil conditions (test group), compared to the use of the chemical drug Metalaxyl (Control group) to eliminate root rot and stem rot disease in durian orchards in the Eastern Region, including Chanthaburi and Trat provinces, totaling 12 crops in an area of approximately 1,200 rai.

The findings of this study and testing revealed that applying G Plus in conjunction with Green Plus was significantly more effective than using the chemical treatment metalaxyl in treating durian root and stem rot disease. A digital microscope was used to examine durian tissue. It was discovered that the tissues in the metalaxyl group (control group) did not alter much. It seems dry, and the red tissue implies infection. There was new tissue development in the G Plus and Green Plus groups (testing group). It appears to be moist.  Recovery from a fungal infection is indicated by yellow or white tissue. Figure 3 shows the tissues of both groups. 

When considering improvement scores (used to indicate improvement in durian symptoms, where 0 indicates no change and 5 indicates a significant change), it was discovered that in the G-Plus and Green-Plus groups (testing group), durian trees show statistically significant (p0.01) signs of change from root rot disease better than the metalaxyl group (control group), as shown in Table 2.
