Two field experiments were carried out at private farm  at Basandela village, Belqas district, Dakahlyia Governorate, during the two growing seasons of 2012 / 2013 and 2013 /2014 to study the effect of foliar spray garlic plants by CuSo₄ (at levels of 0.5 % and 0.1 %), Zn So₄ ( at levels of 0.1% and 0.2 %),Urea( at levels of 0.5 and 1 % ) Borax( at levels of  0.1 %) and some of  their combination as well as fungicide ( Radomil plus ) ( at levels of 2.5 g /Liter), on garlic growth, yield and its components and some chemical compositions of garlic as well as pruple blotch infection of garlic  Cv. Sids 40. The obtained results indicated that : Spraying garlic plants with  treatment urea 1%  or CuSo₄ 0.5 % + Zn So₄ 0.2% + Urea 0.5 % + Borax 0.1% or treatment CuSo₄ 0.1 % + Zn So₄ 0.1% + Urea 1% + Borax 0.1 % or radomil plus 2.5 gm / Liter , produced the highest plant height and lowest bulbing ratio, while these treatments with exception Radomil plus treatment produced the highest value of plant fresh weight.                 The highest cured yield and bulb weight were obtained from spraying garlic plants with treatments Radomil plus or CuSo₄ 0.1% +ZnSo₄ 0.1% + Urea 1 % + Borax 0.1 % or spraying by CuSo₄ 0.5 % + Zn So₄ 0.2% + Urea 0.5% + Borax 0.1%.                 The heaviest clove weight was obtained from spraying garlic plants with CuSo₄ 0.1 % + Zn So₄ 0.1% + Urea 1% + Borax 0.1 % in the first season,  while the treatments CuSo₄ 0.5 % + Zn So₄ 0.2% + Urea 0.5% + Borax 0.1 % gave the highest weight in the second season.                 Spraying garlic plants with CuSo₄ 0.5 % + Zn So₄ 0.2% + Urea 0.5% + Borax 0.1% or CuSo₄ 0.1 % + Zn So₄ 0.1% + Urea 1 % + Borax 0.1 % produced cloves with contents of the highest percent of nitrogen, phosphorus and potassium. These two treatments, also produced cloves contains the highest ppm values of Cu, Zn, B.                 The highest values of chlorophyll A,B were obtained by spraying with Zn So₄ 0.1 %  or CuSo₄ 0.5 % + Zn So₄ 0.2% + Urea 0.5 % + Borax 0.1 % or CuSo₄ 0.1 % + Zn So₄ 0.1 % + Urea 1 % + Borax 0.1 % , while  the highest values of carotenoids were obtained when garlic plants were sprayed (   CuSo₄ 0.1 %  or Urea 0.5 %  ).                 The aforementioned last two treatments CuSo₄ 0.5 % + Zn So₄ 0.2% + Urea 0.5 % + Borax 0.1 % or CuSo₄ 0.1 % + Zn So₄ 0.1 % + Urea 1 % + Borax 0.1 %  in addition to Radomil plus treatment resulted in the lowest disease severity and incidence of purple blotch.
