In order to study the impact of nutrients, secondary metabolites of Xinjiang Wild Apple (Malus sieversii (Lebed.) Roem) on the threat of Agrilus mali Mats., this study took individual wild apple trees with various degrees of pest resistance as experiment material to find the relationship between...

Two different pest control programs were applied on 8-year-old 'Ryoka'/M.26 apple trees (Malus domestica Borkh.). Lime sulfur or Bordeaux mixture with emulsified oil were applied 12 times from late March to mid-September as organic treatment, and synthetic chemicals were 7 times applied as control...

Sunburn is a major type of solar radiation injury that leads to significant economic losses in several fruits, including apples. Here, the efficiency of a new product, called 'Sun Protect', in protecting apples (cv. Granny Smith) against sunburn was tested. The effect of 'Sun Protect' application...

The effect of two-spotted spider mite populations (Tetranychus urticae Koch) on the yield and growth parameters of the early-season apple cv. Katja was evaluated during a 3-year study. In the case of the colonisation of apple trees exceeding 1,462, 2,760 and 1,548 cumulative mite days (CMDs) in the ...
