“…In particular, early blight and powdery mildew cause the most damage in the South of Tamaulipas (27) and Sinaloa, Mexico (8). Insects, such as white flies and various worms cause severe damage in multiple provinces of Ecuador (4) and in the Ivory Coast, Africa (31). This reaffirms that tomatoes are susceptible to a variety of insects and diseases (25), that if not prevented and/or controlled, cause substantial yield losses and severe economic impacts.…”

Pesticides increase agricultural productivity worldwide. Unfortunately, these pesticides put public health and the environment at risk. This study aimed to document the presence of pests and diseases in tomato crops, the range of pesticides used, and acute pesticide poisoning symptoms (APP) among producers from various municipalities in the State of Oaxaca, Mexico. Surveys were applied from 2019 to 2021. The information was examined through a descriptive analysis. The Mann-Whitney U test and Spearman’s Rho correlation established differences between groups and associations. The main pests were the white fly, various worms, blight, mildew, and weeds. Fifty-five active ingredients (AI) were identified, predominantly Toxicological Category (TC) IV, such as insecticides and fungicides, as well as TC III herbicides. Factors associated with a greater diversity of AI were <10 years in agricultural activity, high presence of pests and diseases, and surfaces >1 ha. Up to six APP symptoms occurred in 60.6% of the producers, and 58.2% of the AI identified are considered hazardous pesticides. Highlights: Fifty-five active ingredients were identified in tomato crops, predominantly insecticides and fungicides. More than fifty percent of the active ingredients identified are considered hazardous pesticides. Up to six acute pesticide poisoning symptoms occurred in 60.6% of the producers.

“…Dry and wet seasons also alternate, with mean temperatures ranging from 24.65°C to 27.75°C (Konan et al, 2022). Bédiala is characterised by four seasons, two rainy seasons and two dry seasons (Tonessia et al, 2018). The average annual temperature is 25.6°C (Adjiri et al, 2019).…”

The genetic diversity of a genetic resource is an indicator of its richness and offers many possibilities for improvement. Cowpea is an important source of nutrients for humans and animals. This study aimed at assessing genetic diversity and relationships present among 135 accessions in the Centre National de Recherches Agronomiques (CNRA) collection, using qualitative traits. Traits analysis revealed significant genetic variation between the studied accessions through high Shannon diversity index. Estimated for 15 morphological characters with 0.80 mean value, H' ranged from 0.55 to 1. Seed traits generally expressed mean high diversity index (0.70-0.89). Between 15 parameters assessed, 12 exhibited the most discriminating variability of collection. The three MCA factorial axes explained 19.085% of phenotypic variability. The trait seed colour being correlated to these axes could be used as a selection criterion for local cowpeas improvement. Based on MCA and HAC methods, these accessions were classified into three distinct groups. Containing most accessions, subgroup Ia includes all seeds, pod, and flower colours. Almost all accessions of subgroup Ib possessed creamcoloured, smooth and globose seeds. All cluster II accessions have a creeping habit. The CNRA collection being very diversified, it constitutes a useful resource for future cowpea improvement studies in Côte d'Ivoire.

Objective: The aim of this research is to reflect briefly on the importance of the use of agrochemicals in the productivity of some crops according to their contribution to yield, and some implications of their agricultural consumption. Design/methodology/approach: Based on related literature and some experiences in the field on the use and consumption of pesticides. Results: Pesticides are synthetic, microbial or derived organic compounds used in plant growth programs to prevent or control pests, diseases, and weeds. Also, mineral nutrition (with macro and micronutrients) is considered as agrochemicals. However, the effects on the contamination of soils, groundwater, lakes, seas and oceans due to its use is increasing. Mexico is a large consumer of fungicides, insecticides, fertilizers and herbicides for agricultural uses. Limitations on study/implications: Unmeasured use of any type of pesticide can produce tons of pesticide-trash. Some traces of active or inert ingredients can be detected in bodies of water. Findings/conclusions: The constant risk of agronomic yield losses can be substantial without the use of agrochemicals. Without the application of pesticides, yield losses can reach 100%.
