“…Kaolin is a white, non-abrasive, inert aluminosilicate mineral which serve to reduce insect pest populations by repellency, disruption of feeding and oviposition [6]. In view of the present study, we may conclude that kaolin technology can be combined with another plant protection measure in order to keep aphids population under control in cabbage.…”

Abstract:Infestations of the aphid Lipaphis erysimi Kalt.cause a mean yield loss of cabbage that varies from 35.4% to 73.3% depending from agro-climatic conditions. To control this pest insect in Sub-saharan Africa, synthetic chemical insecticides are usually applied. Kaolin is a white, non-abrasive, inert aluminosilicate mineral that has been shown to effectively protect host plants from insect pests including lepidopterans, sucking insects and mites. The present work is aimed to study the effects of kaolin on the population dynamics of L. erysimi for the Integrated Management of this insect pest in cabbage. To carry out the present study, kaolin powder was dissolved in water to obtain a concentration of 5% kaolin. The plants were sprayed with kaolin suspension every week and every 4-days in 2 respective experiments. Results showed that kaolin sprays significantly reduced aphid populations density. Nevertheless, more frequent applications (every 4 days) did not improve kaolin efficacy. It is concluded that kaolin technology should be combined with another plant protection measure in order to keep aphids population under control in cabbage.

“…5. According to Unruh et al (2000), reduced number of codling moth damage was noticed on the apple fruits with kaolin film in compare with the control results. Kaolin clay particles do not kill pests but repellent them or act as barrier (Glenn, 2016;Glenn et al, 2002;Showler and Sétamou, 2004;Lapointe, 2000 In this study, a highly significant negative correlation between yield and fruit damage was recorded.…”

Abstract. Codling moth (Cydia pomonella L.) is one of the most important apple pests which population is steadily growing. The aim of this study, conducted in Eastern Croatia, was to determine the efficiency of two biological preparations CpGV and kaolin clay compared with pyrethroids and control treatment. The preparations used in treatments were: 1) Cydia pomonella granulovirus (CpGV), 2) deltamethrin, beta cyfluthrin and alpha-cipemetrina, 3) kaolin, 4) control treatment, applying in two different methods of time control, on the three apple varieties 'Melrose', 'Jonagored' and 'Golden Delicious' clone B. The efficiency of the treatment 1 (CpGV) ranged from 78% to 95%, of treatment 2 (pyrethroids) from 96% to 97%, and treatment 3 (kaolin) -between 21.5 and 57%. There was significant negative correlation between yield and damage (r = −07.56). Two methods of determining time control did not differ significantly. Variety 'Melrose' had the highest number of fruits damage in all three years and 'Golden Delicious' clon B the lowest number which can be related to the codling moth caterpillar affinity to a certain variety. It is very important to make the best choice of preparations in control and at the same time be sure of their positive effect on the environment and human health.

Kaolin is sprayed onto plants as a liquid suspension while water evaporates leaving kaolin as a white porous protective powdery film on the leaves surface.…”

he effect of kaolinite and diatom sediments (DS) were applied as crud natural products for soil addition at rates of 2.5 and 5 ton/fed and/or as commercially products for foliar spraying these products are kaolin (Super Nano) and diatoms forms at concentrations of 2.5 and 5% against some potato pests as insects leafminer fly (Liriomyza huidobrensis), and aphid (Myzus persica) as well as early blight disease caused by Alternaria solani, also to study their effect on growth, plant leaves area (cm 2 ) and fresh and dry weight/plant as well as, leaves area index (LAI) and net assimilation rat (NAR) in addition to chlorophyll content measured after 45 and 75 days from sowing, yield and its components (tubers number/plant, average of tuber fresh weight and yield/plant, plot and feddan) as compared with traditional agricultural practices on potato crop (Solanum tuberosum L.) Daimond variety. The experiment was carried out under the desert conditions (Eastern part of Al-Ismailia governorate within Sinai) in split block design. The results cleared that the diatoms and kaolin (Super Nano) as foliar spraying were the superior effect at 5% concentration on cumulative leafminer, aphid infestations and early blight disease incidence and severity. The highest reduction of soil additive treatment against leafminer insect was obtained from diatom sediments (DS) at 5 ton/fed, followed by diatom sediments (DS) at 2.5 ton/fed. In case of aphid leaves infestations as soil additives, the highest reduction was (DS) at 5 ton/fed followed by kaolinite at 5 ton/fed. The most effective soil additive to reduce incidence and severity of early blight disease was obtained from diatom sediments (DS) at 5 ton/fed, followed by kaolinite at 5 ton/fed. The interaction T
