It resulted in disunity in concepts of basic terms such as disease, disorder and injury, in different approaches to categorisation and naming of the main types of plant health problems, and in ambivalence in the use of names for plant malfunctions of abiotic origin. Different terms are used with varying frequency for denoting the same phenomenon. The tenor of this article is to submit some suggestions for redefinition of the main types of plant health problems, their new classification and categorisation. We used the following criteria for classification of a wide spectrum of plant health problems: origin of causal agent, the mechanism by which the causal agent disrupts plant health, and epidemiological features. After the analysis of common and different properties of particular plant health problems and relationships between them, we categorised them using three neologisms, namely bioticosis, abioticosis and co-abio-bioticosis. Redefinitions of the main types of plant health problems are presented. A polyfunctional role of animal pests in plant malfunctions is discussed. Besides, examples of proposed common names for plant malfunctions caused by abiotic agents are given. The objective of the submitted suggestions is to support efforts aimed at conceptual, nomenclatural and institutional unification of plant medicine as a theoretical/practical branch.

Erpelding Author-Workplace-Name: Tropical Agriculture Research Station, Agricultural Research Service, United States Department of Agriculture, Mayagüez, Puerto Rico, USA Title: Anthracnose field evaluation of sorghum germplasm from Botswana Abstract: Sorghum anthracnose is a disease of worldwide importance and host-plant resistance is the most practical method of disease management. In this study, 154 sorghum accessions from the Botswana collection maintained by the United States National Plant Germplasm System were inoculated with Colletotrichum sublineolum and evaluated for disease resistance at the Tropical Agriculture Research Station in Isabela, Puerto Rico during 2007 and 2008. A resistant response was observed for 69 accessions in 2007 and for 48 accessions in 2008 with no acervuli development observed on inoculated leaves. The low frequency of resistant germplasm is expected from a region of low annual rainfall. However, disease severity was low for the susceptible accessions with a mean severity of 11% for the 85 susceptible accessions observed in 2007 and 17% for the 106 susceptible accessions identified in 2008. The highest frequency of resistant accessions was observed for the Ngamiland district with 58% of the accessions rated as resistant, whereas the frequency of resistant accessions ranged from 22% to 36% for the other districts. The lowest mean disease severity was also observed for the susceptible accessions from the Ngamiland district with the highest mean disease severity observed for susceptible accessions from the Kgatleng district. The resistant accessions identified in this study would be useful for the development of disease resistant varieties and the results indicated an ecogeographic association with disease resistance.

Environment variables such as temperature and relative humidity were recorded during storage period. Moisture content was found to increase along with the percent incidence of storage insects. The incidence of storage moulds and insects was recorded in all the samples; results showed that storage moulds belonged to Aspergillus species and the insect Callosobruchus chinensis infested the stored samples. The total fat, triglycerides, phospholipids, free fatty acids and peroxide value were evaluated in the control and in samples stored for three and six months. Results showed that storage depleted total fat (1.94-1.75 g), triglycerides (1.46-1.07 g), whereas phospholipids (0.06-0.21g), free fatty acids (0.002-0.01 g) and peroxide values (2.14-4.46 meq) increased. The fatty acid content of palmitic (26.03-23.56%), stearic (7.4-5.46%), linoleic (56.2-45.2%) and linolenic acids (6.9-4.7%) decreased, but oleic acid content increased (8.3-21.6%) in all the varieties during storage.

SHALABY Author-Workplace-Name: Pests & Plant Protection Department, National Research Centre, Dokki, Giza, Egypt Title: Toxicity and biochemical impacts of some new insecticide mixtures on cotton leafworm Spodoptera littoralis (Boisd.) Abstract: The susceptibility to five new insecticide mixtures: chlorosan, feroban, cygron, engeo, and kingbo was studied in the 2nd and 4th instar larvae of the cotton leafworm Spodoptera littoralis (Boisd.). The efficiency and residual effects of these compounds against S. littoralis under field conditions were also investigated. Obtained results revealed that feroban was the most effective compared with the other toxicants, while engeo was the least toxic insecticide in both instars after 2 and 5 days from treatment. Data also indicated that feroban had the longest half-life (Lt50) while engeo recorded the shortest one. Biochemical analysis showed that the tested compounds caused pronounced changes in acetyl cholinesterase and phenol oxidase.
