Exploration of Efficient Prevention and Control Measures for Husk Spot Disease in Macadamia
Explore the effects of different pesticide application methods(spraying carbendazim+methyl thiophanate,ground spraying carbendazim,ground spraying methyl thiophanate)and additional measures(spraying allicin,applying plant pro-tective film,spraying quicklime,covering plastic film on the ground)on the prevention and control of husk spot disease in macadamia.The results showed that the incidence rate and incidence index of each treatment were significantly lower than those of the control,and the control effect was 27.59％～85.30％.In different application methods,the incidence rate and in-cidence index of husk spot disease in spraying treatment were the lowest,and the control effect was the best,reaching 85.30％,significantly higher than that in spraying treatment;The additional measures did not significantly improve the con-trol effect of each treatment.Compared with normal spraying of carbendazim+methyl thiophanate,adding allicin and cover-ing the ground with plastic film would significantly reduce the control effect;The phosphorus content in the soil of the planting area(111.75 mg/kg)is much higher than the suitable planting range for macadamia(10～20 mg/kg),and there is a lack of elements such as calcium,magnesium,and boron.In summary,spraying carbendazim and methylthiophanate meth-yl on the husk spot disease of macadamia can achieve good control effects without the need for additional control mea-sures.Different planting areas can be fertilized reasonably according to soil fertility conditions.
