Effect of some natural products on productivity and some pests of cabbage

Abstract EN

The study were conducted during two consecutive seasons of 2018 and 2019 in a private farm at Marsa Matrouh Governorate which located in on Egypt northwest Mediterranean coast (latitude 31o 21’ N, longitude 27o 14’ E) to evaluate the effects of Kaolin (Aluminum phyllosilicate [Al2Si2O5 (OH)4]), Bentonite (Calcium aluminosilicate [Al2O3SiO2H2O]), Atabouglite (Magnesium aluminosilicate [Al2Mg3O18Si6]) products as well as chloropyrophose pesticide as foliar spraying and potassium fertilizers as soil additives on cabbage growth, yield, quality and pests control.

Although foliar spray treatments did not have any significant effect on growth characters, chemical insecticide treatment produced the highest average head weight and highest yield compared with other foliar spray treatments.

High rate of potassium supply as 75 kg gave the best value of growth and yield as well as quality characters followed by 50 kg then 25 kg compared with control treatment which produced the lowest values.

Cabbage plants treated as foliar spraying with atabouglite, kaoline formulations exhibited high decrease of aphid population compared with bentonite application which gave the least potential towards adult of aphid insects.

Also, atabouglite had a superior effect on average cumulative cotton leaf worm Spodoptera littoralis (Boisd) infestations of leaves and larvae followed by Kaolin.

Bentonite had the lowest effect.

While, chloropyrophos (chemical treatment) reduced the infestations in highly effect compared with all treatments.
